This has been stumping me for weeks; I must not have the right books. Even my mortifying old Letraset catalog doesn't show it. I think this is also the typeface used for the wordmark of Genentech, but I could be wrong (by now this logo must have been scanned and re-drawn a number of times). I see differences in the n's in these 2 images, but the logo could have been customized. The signage is from the parking garage at SFO.
In any case, I recall seeing this design a lot more when I was a lad (which would be the 1970s). I can't find it, but I'm quite sure it was a retail typeface. Does anyone remember it?
