The picture I was using to create this costume was not especially good, but I did make one glaring accidental omission (which I literally did not realize until I came to post it): I forgot to put on his shin guards! Football before the turn of the century (and well into the early decades) was pretty brutal business. Players wore padded vests and pants, leather shin guards, and eventually leather shoulder pads (this costume has some shoulder padding). Players did not wear helmets.
I might go back and add the shin guards, or I might just be lazy about it. Not sure why I forgot to put them on.
I have not read many of these stories, so I can't tell you particularly what this issue is about, but I am fairly confident Frank wins the day honestly despite some unsportsmanlike effort from his opposition.
