Abstract
A toy construction having a toy element which is preferably embodied in a toy character figure, and a liquid crystal identification element on the toy element. The identification element is operative by the application of a small amount of heat thereto to change it from a non-displaying condition wherein an identifying image thereon is imperceptible and a displaying condition wherein the image is clearly visible. Hence, the identity of the character figure is normally concealed but can be readily revealed by a child when desired.
