Music Rehearsal Studio out back shares space with NCAA football and BBL jerseys, Euro Football/Soccer, NFL, NHL, MLB, and NBA jerseys on the wall, surfboards, skateboards, and skis hanging on the walls and from the rafters. I also have my old competition bibs hanging back there.
Here's a reject quiver photo.. has the bibs on the right, skateboards scattered about, and some music stuff behind the skis.. The skis are usually hanging on a different wall (the wall of 30+ jerseys)on hooks of 2 pair each and from hooks in the rafters.
I used to have a wall of trail maps at my old house I regret not being more careful with them when I moved. I may someday go online and acquire some images to print a frame what is still available from places I've been but having the actual classic vintage tattered genuine articles that may even have some water spots from using it on a big snow day is pretty cool.
Oh, and I also have hats from several places, get one every time I ski new place now. Those are also hanging back there with the jerseys.
