Searching for art to fill your house can be a very expensive task but not when you have the help of the New York Public Library!!!! The digital gallery provides free and open access to over 700,000 images, all you need is a printer. I had fun searching through the vast collection and here are a few of my favorites.....
I just did a search for sports team and came up with these. They have the Brooklyn Dodger football team, Wesleyan University basketball team cira 1903, John Hopkins lacrosse team cira 1928, and the Haverford cricket team cira 1926. Restoration Hardware has old vintage sports teams for sale right now just like these, I think they would look really cool in a man cave.
I also got this idea from Restoration Hardware, they made a gallery of sketched face in a bedroom with individual different type frames - it looks very vintage and very unique.
