One hundred years ago, these young men had the swellest tent in camp, that’s to a little bit of ingenuity and some Eveready dry cells.  In addition to the batteries, they just needed a little bit of wire, a switch, a socket, a bulb, and maybe a discarded reflector from a car.

They kept giving reliable light, night after night, and that was swell.  The ad appeared in the August 1925 issue of Boys’ Life.
