While giving his images away were part of the deal, Ray was always cautious when it came to dealing with money and "ownership". On the one hand, he could be very playful on the matter, but he also took it seriously when people used his images without his permission- particularly when the results did not meet with his approval.
Let me take this opportunity to say that the work you see in this Internet project is presented as a tribute to my friend, Ray Johnson, and consists (unless noted) of images sent to me by him. Please join me in respecting Ray's originality and integrity.
