This comic pack was recently spotted along with the Sabretooth/Wolvie one. (Click the title to see the thread) And if you look very closely you'll see that it says "X-Men First Class Comic Packs" on the packaging. Even the "M" on the top of the card back is an "X".
In the past we've had the "Greatest Battles" and Secret Wars" packs and they have been clearly labeled as such. This is a good thing. I'm sure we will see some X-Men from that poll I mentioned on my blog show up here.
