A framed Egyptian Papyus painting:
A neon t-rex skull I painted:
Old school star wars poster:
I've got a Fullmetal Alchemist wallscroll, a poster for the musical Kiss Me, Kate, and some assorted posters from old gaming and music magazines.
Oh, and my friend owes me a Scott Pilgrim vs. the World poster.
I love my walls. It's mostly Harry Potter... I've ordered a Doctor Who van-gough poster though! so pumped.
