The hat in the foreground of the picture has a diamond shaped insignia which was used by the Royal Artillery during WW2.
A soldier stands shaving in front of an armoured vehicle while a smartly dressed officer is keenly observing another soldier bending over a pot, perhaps making tea or coffee. In the foreground, we can see a bombed out vehicle with its contents scattered on the sand, next to the vehicle is a grave which suggests it may belong to the driver of the vehicle. In the far distance, there is a tank maneuvering away from camp.
The watercolour is beautifully drawn and finished. The picture has not been signed but there were many British artists working in Africa during the war; Edward Bawden, Edward Ardizzone, Anthony Gross, Ivor Beddoes, Edward Copnall, and Henry Carr, to name a few.
