A method and apparatus serving either as a retrofit kit or new sign front for beverage vending machines to allow the display of product contained in the machine by means of significantly larger product identification indicia than the existing product identification indicia and the display windows are specifically correlated to selection mechanisms associated with the larger windows and may also include numbers, letters, symbols, connecting lines and/or colors. The existing selection operatives are deactivated and a vandal panel corner is optionally applied to the machine to eliminate product selection switches. A circuit board is added that enables increasing the number of product selections and it is adapted to be used with different manufacturer's machines. Reinforcement bar means is optionally provided for the signage panel. A holder may be provided for flavor label cards that is exclusively attached to the rear of the signage. Alternatively, audio and/or visual effects are added to the machine. In a new vendor door the appearance of a center column machine may be established with the sign front and strengthening of the center column panel along with enhancing security of the machine.
