Rare, “Voice View”, Collectors, 1990’s, Advertising Mug With Two Logos.

This very rare piece of advertising measures 3 inches high and holds 11 ounces of liquid. Its unique design is based on a computer program from the 1990s, which allowed modems to switch between voice and data while on the phone with customer service. It was a gift from a company employee. The Boulder Colorado company is now out of business. (See photos.)
