Electric Air-Ships and Other Games

(patented)

[Illustration]

This is the age of air-ships and electricity, so what could be more
up-to-date than electric "air-ships" that will float and dive and race
around at the will of the operator? In this game Mr. St. John has again
made use of a scientific principle, the "air-ships" being actually
controlled by electricity. They are made to act in a most peculiar
manner, with no wires, no fuss, no danger. They are under perfect
control and can be made to ascend to the ceiling, drop to the floor or
race across the room, as desired. You simply can't imagine how
entertaining it is to see a lot of excited people managing these aerial
racers, each eager to win.

The outfit contains illustrated directions and materials for two
players, including the apparatus for producing the electricity and the
"repeller" for managing the "air-ships" in mid-air. The little
"air-ships" are actually made of metal and they can be instantly formed.
Here's the latest sport for all ages, because the little ones can play
too. Get into the game and be an aviator.
