Font ID request - old 70's logo

[Bobby H]

Most people are very familiar with variations of the Dolby logo. I attached a copy of the original "Dolby System" logo from the 1970's. I'm trying to figure out specifically what typeface was used for the lettering above and below the logo, "Making Films Sound Better" and "Noise Reduction • High Fidelity."

The image sample isn't the greatest in quality, but enough is there to really puzzle me. At first glance I thought it was ITC Avant Garde Gothic. But the "R" is wrong, the upper and lower case "S" is a little different, and the "B" is too wide compared to the sample image. Then I thought it could be Century Gothic, but the 'M" is all wrong and some of the other letter geometry is not right.

I'm not sure what else the typeface could be, but it's obviously something that was popular in 1970's advertising. I don't have one of my old Letraset font books from the late 70's or early 80's handy. I have a feeling the correct typeface would be in there.

I checked my Letraset catalog and it sure looks like Avant Garde Gothic Medium to me. Also Avant Garde ITC Demi.

Looks engraved, no?

This is an old post, but for anyone searching for this info going forward, the font is very likely Avant Garde Book, as the earlier post points out, and the original font for the Dolby logo itself is/was Eurostile Bold if anyone needs. I was reproducing an old cassette tape label recently and the fonts suggested elsewhere on the web were either for the more modern version of the font/logo, or just wrong. For the logo, Eurostile Bold was almost a perfect match, just needed to add a slight stroke in my case. I hope that helps someone!
