1990-91 Idaho Migratory Waterfowl Stamp Pair sequential!

Got a pair of these 1990-91 Idaho Migratory Waterfowl stamps. They feature some swans on the water and still have the plate numbers on the side. These are the $6 face value ones from back in the day. Pretty cool little piece of Idaho history if you're into collecting duck stamps or state hunting memorabilia. They look to be in decent shape, just been sitting around.
