Invader

Identity and practice

Invader is a pseudonymous French street artist born in 1969 whose work centres on ceramic tile mosaics installed in public spaces across the world. Operating under this alias to preserve anonymity, the artist draws directly from the pixelated aesthetic of 1970s and 1980s 8-bit video games, translating digital imagery into physical form through carefully arranged tiles. The mosaics frequently depict characters and motifs from classic arcade games including Space Invaders, Pac-Man and Super Mario Bros, with the titular aliens from Space Invaders forming a recurring signature element. By December 2020, Invader had placed works in highly visible locations across 79 cities in 20 countries, each installation forming part of what the artist terms an Invasion. These citywide projects are documented through books and maps that Invader publishes as guides, allowing viewers to locate individual mosaics within the urban landscape. The practice sits firmly within the street art movement, combining elements of graffiti culture with pixel art and a systematic approach to public intervention. The work engages with both the history of video gaming and the tradition of unsanctioned public art, creating a dialogue between digital culture and physical space.

Formats and market distinctions

Invader's output divides into several distinct categories that command different attention in the saleroom. The ceramic tile mosaics themselves exist as unique works when removed from their original street locations or created specifically for indoor display, and these carry the highest value due to their direct connection to the artist's primary practice. Invader also produces editions in various formats, including prints, multiples and smaller mosaic works created in limited runs. The scale of a work significantly affects its market position, with larger mosaics requiring more complex fabrication and installation. Support varies between pieces intended for outdoor placement, which use weather-resistant materials and adhesives, and those made for interior settings, which may employ different substrates and mounting systems. Edition size plays a crucial role in valuation, as works produced in smaller numbers or as unique pieces naturally attract greater collector interest. The distinction between street-removed works and studio-created pieces also matters, though authentication of provenance becomes essential in either case. Prints and paper-based editions form a more accessible entry point but represent a different relationship to the artist's core methodology than the tile mosaics that define the practice.

Valuation considerations

When examining an Invader work for valuation, a specialist begins with confirming the medium and construction method, as authentic tile mosaics display specific characteristics in their assembly and materials. The period of creation matters considerably, with works from earlier Invasions often carrying historical significance within the artist's development. For editions, the total number produced and the individual numbering of the piece under examination directly affect value, and a specialist will verify these details against known records. Signature and marking practices vary across Invader's output, and the presence, location and form of any signature require careful documentation. Condition assessment focuses on different factors depending on format: tile mosaics may show losses, cracks or adhesive degradation, while prints face the standard concerns of paper conservation including fading, foxing and handling damage. Provenance documentation becomes particularly important given the nature of street art, where the line between authorised removal and theft can blur. Any history of exhibition, publication in the artist's own maps and guides, or documentation of original installation strengthens a work's position. The specialist also considers whether a piece was created for the street or the gallery, as this distinction affects both authenticity verification and market reception.

Results at this house

LLB Auction has offered four works by Invader, of which one sold. The single realised result achieved 5136 EUR, which also represents the lowest, highest and median figure for the artist at this house. This limited sample reflects the relative scarcity of Invader's work in the auction market and does not permit broader conclusions about the artist's performance across different formats or periods. The small number of lots handled means that collectors and sellers should view these figures as a starting point rather than a comprehensive market picture. The single sale provides one data point within a specific context of date, format and condition that may not apply to other works. As the artist's practice continues and more works enter circulation through both primary and secondary channels, a fuller picture of auction performance may emerge over time. For now, the results indicate that Invader's work has appeared at this house but in numbers too small to establish patterns across different price levels or work types.

Submitting a work for assessment

A seller approaching LLB Auction with an Invader work should prepare comprehensive photographic documentation before requesting a valuation. Clear, well-lit images of the front of the work are essential, showing the overall composition and allowing assessment of the medium and condition. Photographs of the back or reverse are equally important, as they may reveal mounting systems, labels, stamps or other marks that assist with authentication and provenance. Any signature, whether on the front or back, requires its own detailed photograph that captures its form and placement. Labels from galleries, exhibitions or previous owners should be photographed individually, as these contribute to provenance and exhibition history. Accurate dimensions are necessary, recorded in both height and width, and for three-dimensional works, depth as well. The seller should note the units of measurement used. Any accompanying paperwork strengthens a submission: certificates of authenticity, purchase receipts, exhibition documentation, correspondence with galleries, or inclusion in published guides and maps. Information about how the work was acquired and its ownership history provides context that assists valuation. For tile mosaics, details about whether the piece was created for indoor display or removed from a street location form part of the assessment. This preparation allows a specialist to provide an informed response and determines whether the work suits inclusion in an upcoming sale.
