If you have the Oldage Mutant Nasty Turkeys card with a Checklist, it's probably the Tattoo Skins version and your Series 1991 set is not complete. (The same thing is true of #28 Newpork & #32 Pit Milk.)
This will be sent to you via USPS 1st Class mail with tracking.
Please ask all questions prior to purchasing.
Thanks!
