W.H. Taft, 27th President of the United States (1909-1930).
Presumably there was a whole series of American presidents to collect. You can just imagine some poor kid, hoping for Washington or Lincoln, and then going - 'Oh no, not Taft again!'.
However, I was rather pleased with the random nature of this figure when I found it in a collection of small plastic toys I got from Etsy.
