Not the same design as the currently listed cards on their websites with the vertical card and a large feather. This is a horizontal card with space for a player photo on the right. Not sure if some sort of higher level card or an earlier/later issue, etc. If anyone has more info on this card and where it should be listed in issue order please let me know. For now, I've listed it in the guides along with all the other Social Club cards in the same issue. I actually called the casino and all the people I talked with didn't remember this card but I was able to confirmed that the latest Social Club cards from the Seneca casinos are generic cards used at all three locations: Allegany, Buffalo Creek and Niagara.
Here's scans of the new found card...
