1983 Delaware Duck Stamp ($5 Canvasbacks) Mint single never hinged

Got this 1983 Delaware Migratory Waterfowl Stamp for sale. It's the $5 one featuring the canvasback ducks. It says void after June 30, 1984 on the side. Pretty cool piece of Delaware hunting history if you're into collecting duck stamps or just like the artwork. It's in decent shape, still has the perforations and everything. Let me know if you want it.
