All three have the regular back but all are mis-cut and have a ragged right edge. I don't normally go after these sorts of variations but this is a nice 'add on'.
As I was flipping through the binder I came across this wonderful Charlie Dressen which is #56 in the set. I don't know why I haven't posted it in previous looks at this set. The Dodger manager sits on a folding stool with what I believe is a 1950 Oldsmobile in the background. It's not Jim Brown's Caddy but it's still cool.
