Is that an Incredible Hulk top sheet hung over the doorway like a curtain?  Sweet!

hahah, I was trying to figure out what was going on there too. I thought at first those were sheets thrown over the windows to keep evil dreaded sunlight out. But I think you're right, it's a stylish doorway dressing, like a Japanese screen. It looks to be a sheet of several superheroes, I also see Spiderman- but who the hell is Ghost Rider?
