Punch and Judy Theater Hides Camera from Children (Jul, 1942)

This is actually a really good idea.

Punch and Judy Theater Hides Camera from Children
Getting young children to pose naturally indoors for a portrait is far from easy, as many amateur photographers have discovered. If much work of this type is to be done, it pays to follow the example of successful professionals and give the children something interesting to look at. In one studio devoted to child photography, the camera is set up behind a Punch and Judy theater. The children are fascinated by the puppets and pay little or no attention to anything else, so that it is a simple matter to take their pictures.
