"A moment later, Jeanne-Claude sternly warned [newspaper photograher] Tiernan that pictures of the artwork are trademarked and can't be sold." Recall that Christo and Jeanne-Claude are financing the $21 million cost of The Gates entirely themselves. So I understand their desire to monopolize the commercializing of photos of their art. It's awkward for sights in a public park to be restricted in this way. Is this a trend? Compare the Chicago Millennium Park's agreement with one of its artists.
Will the NY Times not sell its reporters' photos of The Gates later through its Archives services?
