The display unit consists of a holder (1) with a slot (5) through it, and a card (7) which is folded in half and inserted in the slot to receive a small notice. The holder has a flat rear surface (2) and holes (4) for fastening it to a supporting surface e.g. a wall, and the card has shoulders (11, 12) on its two halves to keep it in the slot.
