The question has transcended generations of baseball fans, and still generates laughs. This double-sided 10-inch record features a label heralding "Abbott and Costello's 'Who's On First?' Presented to National Baseball Hall of Fame Museum, Cooperstown, NY, 1956." The album itself is an unusual yellow variation, and side 2 is signed in black steel tip fountain pen, "To Tommy, your pal, Bud Abbott." The record is in EX-NRMT condition and in paper sleeve, and included is an 8x10" photo of the comedic duo.
