An instruction board (10) is disclosed providing multiple pictorial presentations (76) in a column, with each including written presentations (78, 80) and voice modules (60) in two languages such as Spanish and English. The pictorial and written presentations (76, 78, 80) are printed on a thin, flexible, and water resistant label (14) secured to the front (16) of a hollow body (12) and extending over and sealing speaker and switch openings (38, 40). Voice modules (60) in the form of panels are mounted by their opposite peripheral edges by strips (66) of double sided adhesive foam tape such that the label (14) vibrates by the air movement within the hollow body (12) by the vibration of the speaker (64) of the voice module (60). The switch openings (40) are generally U-shaped defining a lever (44) integrally extending from the front (16) and terminating in a head (42) carrying a relatively rigid spacer (46) which engages and actuates a switch (62) of the voice module (60) when the head (42) is pivoted about the lever (44) by the deflection of the label (14) into the switch opening (40). The back of the hollow body (12) is formed by first and second back panels (20, 22) which integrally terminate in L-shaped extensions (26), with spacers (32) formed by adhered layers (34) of corrugated cardboard secured to the free leg (30) of the extensions (26) and acting as an anvil for the relatively rigid spacers (46) sandwiching the switches (62) of the voice modules (60) therebetween.
