This is a rather rare photo of Field Marshal Erwin Rommel carrying his Leica camera on the front (this photo was most likely shot during the campaign in France in the summer of 1940 when Rommel was still a general). Rommel was an avid enthusiast photographer who must have amassed a significant number of WW2 photos, whose fate is still undetermined.
