it was kind of weird -
they told me it was "secret" like the color of paint on their walls. then i was told the images were made through "their creative group". i asked if they were a department in their company, or a vendor that did the work for them - dead silence. i asked for the public relations department, a supervisor or anyone else ( read: that might have more of a clue) and they refused to do anything but tell me "not to call back".

clay - can you do gum prints on glass? if you look close at the corners of the images it looks like emulsion coming off of glass ...

thanks for your insights too - gary, brian and ann.
