This is a outstanding original group of 21 lithographs titled Panzergrenaderie dating from 1941/2 by the artist Walter Gotschke they show great scenes of combat  with panzer Grenadier, mechanised infantry mainly on the eastern front.All the prints are contained in the original cover. Unfortunately, the main cover has become detached but still in great condition. This is the first time I've had these and there does not seem to be many around. Please view photos and they measure 33 x 27 cm.
