I do not think this is a pack pulled auto. Almost certain its not, not sure if its authentic either. I have seen many of these UNSIGNED. I had a box full of some old school offbeat cards like Gargoyles, TMNT, ETC. I do not think it is legit.
A. During this series there werent any numbered autos
B. The set checklist doesnt provide ANY info on these existing.
Box Break: Gargoyles: Series One (SkyBox, 1995) (Retail) - Trading Cards News and Resources - Trader Crack's
Above is the checklist.
It may be an IP auto, but if it is a "celebrity" auto putting any numbering on it would be somewhat suspicious.
