The cards in this 33-card set measure 2 1/2" by 3 1/2". The 1961 Golden Press set of full color cards features members of Baseball's Hall of Fame. The cards came in a booklet with perforations for punching the cards out of the book. The catalog designation for this set is W524. The price for the full book intact is double the complete set price listed. Some collectors believe that the three cards which appear on the cover are more difficult to obtain in high-graded third party professional graded condition than the other cards in this set.
