The things I most enjoy on our walls are oil paintings an artist relative of mine did that were passed down to me from two generations before me. A lot of other family members got some of his artwork as well.

If you looked in my den you'd find a host of car photos on the walls. My favorite being one signed by Vic Elford of him driving an Alfa T33 at Sebring dicing with Nino Vaccarella leading a field of other cars.

EDIT: I just remembered that I once bought a large poster of an E36 M3 in a race but got rid of it because it was just too big for the room.
