This is a vintage 'Guilty' Barbra Streisand & Barry Gibb pinback button. It measures 2 inches in diameter. There is a small outdented mark on the metal next to Barbra Streisand's curly hair, so the button is not in perfect condition. The pinback is rather rare, however, and I am sure it will be difficult to find another. It will be insured for shipping. Thanks for looking!
