The American Fireman figure came in three sizes, from just over 4" to just under 9". Often this figure was called a Canadian Fireman in the U.K., probably because it wasn't an English uniform so they guessed Canadian. But recently a Currier and Ives print, dated 1858 and titled AMERICAN FIREMAN, was sold at Skinner (for $1100); I think it's the source material for the figures. Don't you agree?
