Are you willing to put a little bit of money into it? Not necessarily a lot, but i think getting a quality picture framed for a theatre room would look tight!! I put autographed sports photos in my office and frame them.....its my pride and joy of my whole home.
Of course, when it comes to my collection, i am very picky on the pictures that I use, and no 'free' photo i can find on the net seems to do the trick. So, i order all my photos from:
Photo File | sports photos and collectibles, Baseball, Football, Hockey,Basketball and more...
