Columbia Records used this font for their 7" vinyl labels and the sleeves beginning in the early to mid 70s and continued through the mid 90s. Not sure if this is even a font. Any guesses?

Somebody told me it was the Pac Man font, but the "M" is distinctly different.

Anyone? I know CBS had some proprietary fonts made back in the day, but I wasn't sure if this was one of them.

One more time...
