Found another variation of the 11th issue Players Club card from the Seneca Niagara Casino

On the originally listed 11th issue card the reverse text over the signature strip is centered with ragged edges at the left and right.

On the new found variation, the cards are basically the same except the reverse text over the signature strip is aligned at the left and right. Both cards have the same PG manufacturer's mark.

Here's scans of the new found card... with a scan of the original back at the bottom
