60s vintage cotton print fabric the Thinker, Omega Psi Phi fraternity

Vintage cotton fabric with the Omega Psi Phi fraternity greek letters and the Thinker. Probably 60s, we think - though possibly earlier? This is 35" wide x well over a yard (almost 1 1/2 yards).

It's been washed, possibly used. It shows a few spots and a couple of maker's flaws. Not perfect, but we'd imagine it's very difficult to find.
