norstar:OK, Thanks!
Reviewing the fields, I think that I can make a reasonable guess on the artists and the kinds of art that can be purchased from my pictures. But I didn't see the name of the person who refurbished the machine and whether this machine is the same that was found, previously.
You can also try to contact the place you found it and ask them whos stuff they got in their machine. Or just pick some names from this page. http://www.artomat.org/artomat_artists.php
I don't think it really matters. It would have been refurbished by Clark Whittington. As far as I can tell there are no others posted in RI. and can't tell if there ever were. There's nothing in the one page of past history. So post that puppy!
