What's the bet that it's bricks and mortars and that it happens, physically, well before the much hyped Jack Kirby Museum? And won't that annoy a lot of people.
Get used to it. Stan is very rich these days, if he wants a museum, he gets a museum. Just what gets placed into the museum is anyone's guess, but it's a good chance that it'll be a lot of art drawn by others, including Jack Kirby.
People, start firing now.
