Full titles read: "SLING SHOT CHARLIE - Here's a modern David - but he uses his son instead of Goliath !"
L/S of man picking up his ammunition form a container in front of him and firing them in the direction of his son. C/U of his son who is wearing an ordinary flying helmet and goggles. However, there is a slight difference! There are also three bulbs attached to the helmet (he does look quite odd!) which 'Sling Shot Charlie' systematically breaks with shots from his catapult, William Tell style. L/Ss of man throwing objects in the air for Charlie to shoot down.
