This changeable copy sign assembly is made up of several wafers, each bearing a single indicium on a relatively opaque background. The wafers and a backing strip are removably retained to a face plate of the assembly at an elongated, window-like opening, and the backing strip is composed of opaque markings for preventing the leakage of light between adjacent wafers.

Toy stores have been stocking the DUPLO, a large-size adaptation of the famous LEGO brick, in either the construction toys' section or the pre-school section, but not in both. To help remind and direct customers, the company is using this dangler that informs them about the product and where it is stocked in the store. The mobile-like dangler is hung by a 5-inch V-folded strip of clear plastic so it extends at an angle of roughly 80 degrees.
