"This undated photograph provided by the Metropolitan Museum of Art shows ""Dress"", made of the museum's admission buttons by Ji Eon Kang, a gift to the museum by Richard Martin. Starting Monday, June 30, 2013, the button will be replaced with a paper ticket with detachable sticker. Museum officials say it has become too expensive to produce the buttons. They were introduced in 1971. The buttons came in 16 different colors and featured the letter ""M."" The color was changed daily. The change comes around the time the Met is switching to a seven-day week. It has been closed Mondays. (AP Photo/Metropolitan Museum of Art)"
