A sign (10) for selectively displaying a variety of information in a viewing window (16) includes a web (52) extending between a pair of spaced rollers (40 and 42) and moveable by rolling and unrolling on the rollers (40 and 42). A base panel (59) is releasably secured to a surface of the web (52). The base panel (59) has an outer surface and an inner surface facing the web (52). Pockets are provided on the inner surface of the base panel (59) for receiving the ends of display panels (122, 124, 125, 126, 127) containing the information to be displayed in a viewing area of the sign (10). The pockets retain the display panels (122, 124, 125, 126, 127) on the base panel (59) while permitting relative movement therebetween as the web (52) is rolled up and unrolled. The attachment of the base panels (59) to the web (52) also permits such relative movement.
