I accidentally found 1976 "Official Caliornia visitor map" scan on Flickr, and would like to know what exactly the main font is (the tri-color upper)? I checked 1977 Letraset font brochure, Linotype website and some retro design websites, but with no results as yet. There's even NO image o that font anywhere else. Kinda strange.
I'd like to try to find and use this font for my design work, so any help would be appreciated.
Thank you and best regards.
