Description

Archimedes Lab (https://archimedes-lab.org/) is the 30+ year-old brainchild of Gianni Sarcone and Marie-Jo Waeber. Over the years, they have produced many puzzle and optical illusion products, including a 4-volume journal, with educational and advertising intentions. They used to produce a series of optical illusion and puzzle cards, which no longer seem to be available through their web site or Gianni Sarcone's RedBubble outlet. I am offering five of their original postcards:

Neth's Arrows — optical illusion in which it HARD to believe that two arrow are the same length

Ants — a counting optical illusion

Black or White — an optical illusion in which one cannot distinguish background from foreground

The Purple Marbles — parallel lines appear to be askew

The Birds — a classic 3-piece vanish puzzle designed by Gianni Sarcone

All of the postcards measure 5 3/4 in x 4 in (14.5 cm x 10.5 cm), and are in mint condition.

I will ship within the US as a non-machinable letter for $2.25, and I will ship internationally as a first class non-machinable letter, which I estimate to cost $6.21. Note that I cannot guarantee that overseas packages can be tracked.

Thank you for viewing my auction!
