Glad to see I'm not the only one freezing BBT and trying to figure out exactly what collectibles they have in the background. They have some good stuff, but also a lot of set designer "eh, it's a Superhero, just stick in it there somewhere " items.
I have a lot of what Wolowitz does in his bedroom, but I'm smart enough not to put them IN THE BEDROOM.
BTW Alcatraz also has a comicbook store set (Jorge Garcia's day job), but they seem to be going the "genetic, non identifible" route.
