I have two Harry Brecheen baseball cards one is 3 3/8 x 5 3/8, I believe it is an Exhibit card #39 1947, the other measure 3 x 4 3/4, what is it? Both look like the same card. They match a 8x10 1947 photo I have. Well 1947 Exhibit is not the same image, but could have been edited. But what with the other size 3 x 4 3/4?
