I've been hoping to find an old foosball game in the dump that I could take apart and reuse in one of my pieces. I did find a small tabletop version...not exactly my first choice:
I hit the jackpot a few days ago, grabbing the full size model almost as it was being thrown from the truck (yes, I'm getting bold).
Combining these foosball player pieces with the old airplane engine, a broken doll, a small drawer, newspapers, etc., I've just completed a new piece. The lower half is covered with glass.
