Its an Italian one, as in Alberto Masi. Been repainted, the paint and the chrome on these was often fragile.
Transfers are later American Masi design versions. Seat tube bands are kind of painter's artist approach to placement.
The market for these is quite varied, as a whole bike, not bad, but Shimano parts? It should be CAMPAGNOLO. Only.
The dogleg seat post is curious, these bikes were not that upright, a typical straight post should work well.
