Lesson 24 : Visual Aids - Charts

Overlay charts

Consists of a number of illustrated sheets which can be placed one over the other conveniently and in succession. The drawing or illustration on each individual sheet forms a part of the whole picture. This enables the viewers to see not only the different parts but also see them against the total perspective when one is placed over the other. When a final overlay is placed the ultimate product is exposed to view. Such a presentation has a dramatic effect on the viewers.
