I saw someone with one of those “patriotic t-shirts” and though of making one of the “Land of the Free Because of the Brave” shirt with pictures of:

Ulysses S. Grant
Susan B. Anthony
Richard Winters (Band of Brothers)
Desmond Doss (The medic Andrew Garfield portrayed in Hacksaw Ridge)
MLK Jr.

There are probably some others to put in, but you get the idea.
