1943-44 La Campaña premium of Negro League HOFer, Martin Dihigo.
One of the rarest Dihigo items with only a couple known to exist. This example is by far the nicest one known. Measures 6" by 9" and features one of the best images of Dihigo around. I believe the last example to sell publicly was in my auction back in November of 2007. Truly rare piece.
