THESE ARE NOT REAL CARDS. I MAKE ALL OF THESE CARDS PERSONALLY. THEY ALL COME WITH A BLANK BACK, AS DO THE ORIGINAL 1959 HOME RUN DERBY CARDS. THESE ARE THE SAME SIZE ( 3 1/4" X 5 1/4" ) AND THICKNESS AS THE ORIGINALS. THESE CARDS ARE MADE UP WITH A FEW PLAYERS THAT WERE IN THE ORIGINAL SET, (WITH DIFFERENT  PHOTOS), AND SOME OTHER SUPERSTARS FROM THE LATE 1950'S AND EARLY 1960'S THAT WERE NOT IN THAT SET. SHIPPING IS $2 FOR UP TO 3 CARDS, OR $3 FOR 4 OR MORE CARDS.
