Tomás Sánchez

Everything LLB Auction has offered by this artist has been an editioned print, lithograph or screenprint, not a unique canvas. The six figure results quoted for this name belong to paintings and say nothing about what an edition is worth. Bron

The 2025 editions are large. El testigo was issued in an edition of 425 and made GBP 625 including premium at Tate Ward in London in June 2026. Edition size, not the artist's name, sets the price at this level. Bron

Large canvases carry real unsold risk at the top of the market. Tambos, a 200 by 250 cm canvas of 1993 estimated at USD 400,000 to 600,000, did not find a buyer at Bonhams in New York in November 2023, and two further canvases estimated above USD 120,000 failed at the same house in May 2024. Bron

Canvases are commonly signed and dated at the lower right and signed again, titled and dated on the reverse. Photograph the verso in full, because the inscription there is what a specialist compares against catalogued examples. Bron

This artist issues certificates of authenticity signed in his own hand, and catalogued lots at Bonhams and Phillips routinely note one. A canvas offered without that paperwork should be expected to be discounted for it. Bron

Two distinct bodies of work carry the name: the meditative lagoon and waterfall landscapes, and the grey landfill paintings begun in the early 1980s. They are collected by different buyers and should not be valued off one another. Bron

The support is not always acrylic on canvas. Oil on canvas and casein on board both appear in catalogued lots, and the medium materially changes where a work sits in the range. Bron
