NCO Stug/PzGren wrapper portrait

NCO Stug/PzGren wrapper portrait. NCO Schirmmütze and Green/Grey wrapper in wear. On unmarked paper, taken at Paul Lobbert Lichtbildkunst Vertrieb Essen. The back reads Unteroffizier Josef Hecker(or Heeker). Nice postcard size portrait that got a bit too much light near the bottom and wasn`t cut like intended.
