A replaceable sign face used in vending machines for operating instructions, advertising purposes and the like. A front panel having optically transparent regions and a curved surface and constructed from a sturdy, solid material serves as a permanent protective cover to deter attempts at tampering and breaking in for food or money. A replaceable inner panel bearing advertising media is disposed directly behind the front panel. The inner panel is formed from a thin, resilient and inexpensive material which is configured for frequent replacement with minimum effort. The transparent front panel and replaceable inner panel bearing instructional and advertising media (hereinafter sometimes referred to as visual displays) are securely held within retainers disposed at either end of the front face of the vending machine.
