Hi everyone! We’ve just moved my boyfriend into my apartment, and while I’ve got the living room, bedroom, and computer room “down” (I’ll post pictures when I get a reliable camera and everything out of boxes!) I’m in need of some help with the dining area. Specifically, there is a large, blank wall behind the table and it’s just blank and depressing.

(I apologize for the bad webcam pic but it’s all I have right now.)
The wall there is about 9′ across. I don’t mind having some whitespace obviously but I’d like to locate a nice, large art print or wall decal or something of that nature without having to spend a whole ton of money on it, just to brighten the area up a bit. I fixed up the living room wall with

(again a crappy webcam picture, sorry, it looks cooler in context but it’s hard to get context with the webcam!)
Does anyone know of a place where you can buy large prints, or a series of smaller prints that link together, without spending a fortune? Or failing that, something that can be done to spruce up the space? Paint is out of the question as you need special permission from the landlord for that.
Thanks!
