A photographer (not me) started a thread on Flickr stating that he tried to sell a picture he took on the New York Subway as a postcard through Zazzle. Apparently the MTA sent a Cease and Desist letter to Zazzle indicating that the image violated its "intellectual property rights". Zazzle would not clarify what the MTA meant although I suspect it is because the train route symbol is trademarked. Has anyone had this experience? Does anyone know if the MTA is objecting only to its logos and route "bullets", which are trademarked or to pictures of any of their trains? Would this also mean that railroad buffs can't sell prints of the pictures they took on the subway? While the route symbol (assuming that is the sole issue) can be edited out using Photoshop it would make the image historically inaccurate. If anyone can shed some light on this issue it would be greatly appreciated since I intend to sell prints and cd's of my pictures at a train buff meet this fall.
