The Cars, Philadelphia, PA, Nov. 24, 1980.

Gemini Computer(AKA Sonic) with a flipped 'E' for a better fit next to the 'T'. The 'O' is also customized, or from a version of the font that differs from this 1980 sample. Ticketron employed a huge range of ticket designs, with various logo variations, patterns, and colors — presumably to prevent counterfeiting. I'm partial to the electronic rainbow dots of 1980.
