1973-1974 $5 Steller's Eider Migratory Bird Hunting Stamp artist signed CV$250

Got this 1973-1974 Federal Duck Stamp featuring the Steller's Eider. It's the $5 denomination and has a signature across the front which is pretty common for these since they had to be signed to be valid for hunting back in the day. The colors still look decent and the perforations are mostly intact. Cool little piece of migratory bird history if you're into stamp collecting or waterfowl stuff. It says void after June 30 1974 so definitely just a collectable now.
