Photo from the certificate of the regimental commissar (?)

The original picture is in satisfactory collector's condition. The reverse side is signed "Papa". The size is 30*37 mm. Excesses, tears. Judging by the absence of emblems on the buttonholes, the person depicted in the photo was a regimental commissar (unlike political workers, doctors, quartermasters and technicians had to wear lapel emblems according to the type of troops). Guarantee of authenticity.
