One of our most popular images seems to be the 80 illusions poster. For everyone wanting a giant version, there’s been one available 35 x 23 inches, on our selling site at www.cafepress.com/optoct. I was pleased with the quality of the printing when I got one. Because of the interest, we’ve now reformatted the layout for a smaller version available on the same Cafepress site, 16 x 20 inches. Both versions have discreet identification under each illusion, so that they can be followed up on this or other sites. They include little known or novel versions of many famous illusions – and one or two illusions that we think are new.
