Definitely part of the Vault "1/1"s (the only difference being the COLOR of the 1/1 stamp on the front).
They released no checklist, no telling of how many of any one cards, just that the red is the first 1/1. blue the second, and so on.
Anyway, if you go to the link avsbruins65 gave you, find a link there for "See an inaccuracies" and enter the information there (and give a link to this forum thread). Someone will get it added for you.
