An early photo of Mordecai Brown taken in 1905 by Paul Thompson early in his career as well. We know it is 1905 based on Brown’s uniform as shown below.
Based on the fact Brown is wearing a road uniform and the background it is believed the photograph was taken in New York’s Polo Grounds. That was Thompson’s home base at the time and the stamp address on back is from his earliest period.
“Iron Man” Joe McGinnity strikes a pose during Spring Training in Savannah, Georgia circa 1904. This image graced the cover of Spalding’s How to Pitch from 1905 and onwards.
Red Faber when the Chicago White Sox trained in Waxahachie, Texas in 1921. The stadium backdrop is Jungle Park.
Large, sharp image of Nap Rucker in 1913 based on the uniform. The annotation on back indicates the photo is from 1913. By this time, Rucker was relying on his knuckleball to get hitters out.
