发明名称 Display sign
摘要 A sign for displaying prices and other information, in which at least one numeral character is changeable to display any numeral from zero through nine. A plurality of flap members are each pivotably attached to a flat foundation portion of the sign by resilient clips which hold a portion of each flap closely against a flat front side of the foundation member, thus holding the entire flap against the front side of the sign to prevent the flaps from being caught by wind. The flaps can be overturned by use of a tool including a spatula-like end, to display selectively a background colored face of the flap, covering a contrastingly colored portion of the foundation member, or to display the opposite face of the flap, which is of the contrasting color, and uncover the contrastingly colored portion of the foundation member. The spring clips are movable to permit the flap to be overturned, yet resiliently urge the flap against the front side of the foundation member at other times.
