Aged certificate and autographed picture!
 
Beautiful reproduction of an early U-Boot-Kriegsabzeichen (Submarine War-Badge) award document for Erich Topp and signed by Karl Dönitz.  
He sank 35 ships giving him position #3 on the list of top U-boot aces of World War II following Kretschmer and Lüth. Topp wrote the battle manual for revolutionary U-boot model XXI (Elektro Boot) and took command of one (U-2513) just before the end of war.
 
Certificate is printed on appropriate thickness/size cardstock paper, aged on both sides. The autographed 4x6 photo comes optionally.
