Enter this 1989 Fleer card of Manny Trillo.
Aside from the top/bottom centering (not my crop job) the fronts are identical.
There error shows up on the back in the demographics box. The corrected card on the left says that Trillo throws with his "Right" while the error says he throws "Rig..."
Like the other errors, I don't really remember which I had in my official collection and which was in my extras box. And again, it's nice to be able to add to my collection from within my collection.
