y- I've seen those Leary signed prints on ebay. Also Kesey signed ones, and once, a Dr. Hoffman signed one (eek!) I would love to have one, but too rich$$ for my pocket right now- maybe someday soon, like when this bee starts dreaming of honey.......
About the printing co. thing.; There are a wide variety of inks out there, for use in undustry. I actually worked at a company that made non-toxic inks for printing food wrappers, and also for stamping foods and drugs (the white "letter" on a certain candy, or the lettering on many drugs. Ask the printing co. if they use inks that won't run when wet, or if they use non-toxic inks (not that the toxins present in a 1/4 inch square of printed paper would be much to worry about- it would be a very, very, small amount, certainly not enough to make any one sick.
