In its 50-plus years of existence, the NBA has showcased some spectacular talent. But through it all, there were four players who dominated, each within their own decades. UDA presents 'Decade Legends,' a limited-edition lithograph signed by Michael Jordan ('90s), Larry Bird ('80s), Julius Erving ('70s) and the late Wilt Chamberlain ('60s). It boasts perhaps the most sought-after autographs in professional basketball, all on one piece. This item is authenticated by UDA and framed measures 25-by-32 inches.
