KB Toys
The fact that Kate and Clint are in an abandoned KB Toys might seem like a bit of simple nostalgia. It also works on the level that K and B are Kate Bishop’s initials. But there’s also a deeper Marvel connection here. During Marvel Comics’ turbulent
business troubles in the mid-90s, Toy Biz (owned by Ike Perlmutter and exclusive to Marvel) greatly expanded their offerings in an attempt to stave off bankruptcy for the company. Many of those action figures were exclusive to KB Toys. When the inevitable happened and Marvel Comics went bankrupt, it was Perlmutter, Avi Arad, and the toy side of the business that took control of Marvel as a whole and put Joe Quesada at the head of the publishing side, which turned its fortunes around. A nice Marvel history egg there!
