I find it interesting that 3 of the 4 jockeys have "Celebrated American Jockey" on the inlay. I guess that is because Tod Sloan, also an American jockey, achieved fame racing in England.

BTW, in the Cagney movie "Yankee Doodle", Geo. M Cohan's first hit, "Little Johnny Jones", was based on the life of Tod Sloan (aka "Yankee Doodle Dandy")
