From looking at it i think that they are a hoax, considering where they popped up ie a connection to the TF2 Guard Dog, but they look dam good.

After putting all the official posters next to the possible ones, all I have concluded is that coach has two differant shirts.

Edit: In both possible posters, he has the same shirt from dark carnival. But he is in nothing like the same position, so this is either an excellant edit or the real thing. Which we knew already....
