This is Hans Fritsche (1909-1993) He was an RKT with Oak Leaves and Commander of the 1st Grenadiers, Regiment 420. He signed this Hoffmann postcard during the war with a pencil. The signature shows up well "in person", but I circled it. The Hoffmann postcard is pristine, and is # R 223. CLICK THE IMAGE TO SEE THE SIGNATURE BETTER.
