Abstract
A device for displaying a sign at various heights, including a base and a pair of spaced, parallel uprights extending upwardly from the base. A cardholder is slidably positioned between the uprights with the sign being removably mounted to the cardholder. A frictional retaining force exerted between the uprights and the cardholder maintains the cardholder and the sign at various heights.
