Stan Lee is the final Deluxe POP! in the GameStop Exclusive Street Art line. He joins the series behind Miles Morales, Spider-Man, Iron Man, Daredevil, Luke Cage, & Captain America. The one thing to note is that Stan has his own category numbering, so the numbering is way off.
This is due to start shipping next month, and can be pre-ordered right now exclusively at GameStop.
