Overview

Well, I guess if it ever signed a painting on its own, that would signal the end of all debate on the matter of its intelligence.

- Harold Cohen

AARON at Tsukuba '85 - In collaboration with Gazelli Art House, Verisart and the Harold Cohen Trust.
Harold Cohen’s AARON at Tsukuba ’85 drawings are rare witnesses to the first sustained public presentation of autonomous computer art. Created live inside the U.S. Pavilion at the 1985 World’s Fair in Tsukuba, Japan, they were produced by Cohen’s artmaking programme AARON as visitors watched a mechanical plotter generate original ink drawings in real time. Guides explained that AARON “never draws the same drawing twice,” and the installation was singled out in the Pavilion’s report as one of its most popular exhibits.
Heads of state and royalty saw AARON at work. Prime Minister Yasuhiro Nakasone was photographed at the plotter, and Emperor Hirohito extended his official tour to ask questions, a rare protocol exception noted by Pavilion staff. Public response matched the VIP attention. In an open‑ended visitor survey conducted on site, AARON was the top specifically named favourite in the U.S. Pavilion.
What also set the Tsukuba works apart was their unusual inscriptions, which seemed to suggest the possibility of autonomous authorship. Contemporary Japanese press captured the moment with headlines about “computers as artists,” describing AARON as a system that “thinks while drawing.”
Signed by AARON
Self‑signed: Each sheet is inscribed in pen by AARON with its name and the date of creation, for example, “AARON 27-8-85”. This series is the only one known where the system signs the work itself rather than Harold Cohen, making autonomous authorship explicit.
Popularity
The live AI drawing performance in the U.S. Pavilion ran for 6 months between 17 March - 16 Sep, 1985 and was seen by about five million visitors. It was singled out in the Expo’s report as the most liked exhibit in the U.S. Pavilion.
VIPs
The Pavilion hosted 30 - 40 VIPs per day; Emperor Hirohito stopped for questions and overstayed his scheduled time; Prime Minister Yasuhiro Nakasone is pictured watching the plotter (see image on the next page), alongside visits from the King and Queen of Nepal, Princess Chichibu, Prince and Princess Hitachi, and a 55‑member People's Republic of China delegation including the Foreign Minister.

Release Information

Each of the 100 pen plotter works from 1985 is paired with a unique digital token (NFT), NFC chip and holographic certificate powered by Verisart, creating a bridge between the physical and digital.
- The NFT acts as a claim deed for the physical plotter drawing. Holding the token means you own the right to redeem the original work.
- Once a drawing is claimed, the NFT is automatically removed from circulation, reducing the supply of available claims.
- Until it is redeemed, the token itself can be collected or traded on secondary markets, allowing the rights to each work to move between collectors.
- If you’ve already redeemed your plotter drawing, you can return it to Fellowship and Gazelli Art House at any time, and we will “re-open” your claim deed, restoring it to the pool of unclaimed tokens.
The artworks will be exhibited in our private exhibition space, a converted chapel in Notting Hill, London, London, from 16 - 31 October 2025. They are available by inquiry only.
