1956-1957 $2 Migratory Bird Hunting Stamp American Merganser artist signedCV$300

Got this 1956-1957 Federal Duck Stamp featuring the American Merganser. It's the $2 migratory bird hunting stamp from that year. This one is signed across the front by the original owner, which was pretty common back then for hunters to do. The edges are perforated and it looks to be in decent shape for its age. Cool little piece of history if you're into stamp collecting or waterfowl stuff.
