In 1916 published Felix Mendelsohn produced two series of black and white photographic baseball cards that were designed with blank backs and also offered to a variety of companies with their advertisements on the reverse. The different sets have become extremely popular among type card collectors hobbyists building back runs and set collectors alike. Long underrated the challenge of completion coupled with the added layers of rarity associated with the various backs have increased collector interest particularly as type collecting becomes more popular. In addition to offering a number of different advertising backs from these two issues our Summer 2015 auction includes a large number of Hall of Famers and key cards with the tougher Famous & Barr advertisement on the reverse. The St. Louis clothing retailer was an early customer of Mendelsohn's M101-5 issue and continued with the M101-4 series. By 1916 any remnants of Rube Marquard's early nickname "The $11 000 lemon" were long gone as he won 20 games in three consecutive seasons between 1911 and 1913 before moving to Brooklyn in 1915 where he would play through 1920 ultimately finishing his Hall of Fame career with Boston. His 1916 season would see him post a 13-6 record in 21 starts with an ERA of 1.58. Clearly a star his Famous & Barr card depicts the smiling lefty in the follow-through of his throw. Graded VG 40 by SGC the primary flaw with the card lies in the top edge where chipping and left corner damage reduce the card's technical grade.
