I have the frame from my 1974 Maino hanging in my basement. It's a road bike of Columbus straight-gage tubing that I bought while working in my first bike shop, and we had many many miles and wonderful adventures together. Given that it needs a 5-speed freewheel and has a couple dings in the frame, it's not worth anything to anyone but me. It could be built up as a single-speed if I wanted. But for now, it hangs there and I have good feelings about it every time I go in my basement.
