THE SUPREMES. Incredible set of vintage signatures in full of Diana Ross, Florence Ballard, and Mary Wilson, all in blue felt tip ink on individual 6×4 white index cards. Very fine condition, with Ross inscribing to John and a small magazine photograph affixed at the bottom right corner of Ballard’s signature card. Pencil notations on the reverse sides indicate that all three signatures were obtained in person on March 1, 1966. Scarce! John Verzi collection.
