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. Graded VG 40 this Famous & Barr example of card #26 depicts Hall of Fame outfielder Max Carey. Carey was a speedster who averaged 48 stolen bases a year during his 20 year career topping out with 63 in 1916 the year this card was issued. While Carey's Hall of Fame credentials are sometimes questioned it is difficult to find fault with a ballplayer who averages more than 100 runs scored per year and 174 hits over the course of 20 seasons.
