Handshake photo of Connie Mack and Charles Comiskey. Shot in 1917 by noted photographer George Burke, Burke & Koretke Studio. Photo is 8" x10" and in NRMT-MT condition with only a very minor edge nick on the lower left corner. Mack is congratulating the “Old Roman” on the Sox pennant victory, which was preparatory to their eventual World Series Championship over the New York Giants that year.
