1913 Aston Villa team after pre-cup game with Chelsea. The three players far right are Littlewood (who did not appear in the cup final), Stephenson, and Barber. Tommy Weston, who did appear in the cup rounds, is not shown.
English: This pre-1916 postcard (that I own) from an old scrapbook claims to show the members of the Aston Villa 1912-13 season English Football Association Cup winning team. The names of the players are listed, but there is a handwritten note which indicates three of the names are mislabeled. The author of the note is not known. Two names have been scratched out, but can be read under magnification. They are T. Barber and T. Weston. The writer has substituted Littlewood and placed Barber at the end after C. Stephenson. Judging from other photos of the team found online, the writer of the note is correct. He says that this photo was taken after that year's game with Chelsea. So, in short, one player, Weston, is missing, and one player who did not appear in the cup final is shown, namely Littlewood.
