Modified running gear of the Sd.Kfz. 101 Ausf. A tank
This photo is one of two that can definitely be said not to have originated with Gruber.
However, it was also taken on the Eastern Front, specifically with Army Group South.
It shows a vehicle improvised by the troops using the chassis of the light Panzer I (Sd.Kfz. 101 Ausf. A) tank. A relative is seated inside the vehicle. These modified vehicles were used for reconnaissance, transport, or towing.
