Card Identification Forum

I have cards from a New York Football Giants team set that have the 2016 Donruss design, but aren't just a packaged release of the base cards that I see exist for sale online.  There is no foil on the front, the script is slightly smaller than the base, and the numbering starts at 1, without an alphabetic prefix.  I can't find a checklist for these, and don't see them online.  I think I bought them on eBay, and I don't have them all together.  I have, in front of me, cards 3 R. Jennings, 4 O. Vernon, 5 S Shepard, and 6 E. Apple.  Would anybody know of a checklist for these, and more importantly, what would I name them if I happen to find the rest of the cards and figure out the checklist that way?  I genuinely have no idea how many there are, or where the rest of mine might be.

EDIT: The cards also lack the NY logo that is in the lower corner on the base cards.

This was a six card promo set given to fans at the Bears vs. Giants game last season. I would assume Odell Beckham Jr is card #1 and Eli Manning is card #2. I do see a Buffalo Bills promo set listed on the database, similar to this one. Is there a sponsor listed on the back of your cards? http://www.tradingcarddb.com/ViewSet.cfm/sid/144623/2016-Donruss-Blue-Rock-Energy-Buffalo-Bills

Thanks SunDevil.  There isn't a sponsor anywhere.  I'll upload the checklist adding the two cards you gave.  I suppose I'll name it like the Bills one, but without the sponsor name.  Thanks for your help.
