The listing, $5.00 Federal Duck Stamp has ended.
Front - "U.S. Department of the Interior. Void after June 30, 1979. Migratory Bird Hunting and Conservation Stamp. $5. Hooded Merganser." You can see the backside faintly reads - "Buy Duck Stamps. Save wetlands. Sing your Duck Stamp. It is unlawful to hunt waterfowl unless you sign your name in ink on the face of this stamp." Pretty neat!
