Abstract
A changeable letter for signs is provided as a part of an illuminated sign or copy board system which provides different appearances when the changeable letters are alternately backlit or frontlit. The letter, understood to include letters, symbols and numerals, includes a translucent plate and first, second or additional layers of opaque, indicia-defining material applied thereto. The second layer is preferably of a lighter color than the first layer, and when superposed thereon, presents the appearance of a lighter colored letter surrounded by a darker border. However, when the letter is backlit as it would appear at nighttime positioned on an illuminated sign, the letter presents a black or otherwise darkened appearance surrounded by the lighted portion of the sign.
