New York City's Metropolitan Museum of Art is doing away with the tiny metal buttons that serve as its admission ticket.
Starting Monday, 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.
