A display button includes a front body member which has an opening or window. A disc-shaped member is rotatably mounted behind the front body member and retained there by a retainer member wedged or friction-fitted into a rearwardly folded circumferential lip or ear of the front body member. The disc-shaped member has at least one slot into which an indicia carrying insert can be inserted either through a slot of the window or of the retainer member. A plurality of distinct and unique indicia are affixed to the disc-shaped member on the side which faces the front body member, positioned so that each indicia can be brought into registry with and selectively displayed through the window.
