ABSTRACT:
A sign for carrying changeable inserts having a metal base plate of resilient material on which are formed a plurality of clips providing gripping engagement of an insert of sheet material to carry said insert removable upon a surface of the base plate. The clips each have a tab integral with the base plate. The tabs each extend above the surface and open onto said surface. Each tab resiliently bears against marginal portions of the insert sheet material for gripping engagement thereof. Said tabs are joined to the base plate by a zone of merger having compound curvature for nonlinear distribution of bending forces upon bending of said tab. Dimples upon opposite sides of each clip coact with the tab for providing more secure engagement of the insert.
