1989 Delaware Duck Stamp

Got this 1989-1990 Delaware Migratory Waterfowl Stamp. It's the $5 one featuring some buffleheads on the water. It's still on the original backing paper as you can see in the photo. Pretty cool little piece of Delaware hunting history if you're into collecting duck stamps or just like the artwork. It says void after June 30 1990 so obviously just for collecting now. Overall looks to be in decent shape for its age.
