That Bret Hart poster might be from 2000. He didn't win the WCW Championship until late November of 1999, so the poster probably wasn't released until December 1999 or January 2000. If it was put out in 2000, you'll need to get that replaced with a 90s poster of him. The NES Wrestlemania poster is definitely from 1989.

*shakes finger at you* C'mon now, we have to be strict on the 1990s theme.
