Need help identifying this amazing font used in a Election Poster by Jim Trelease for the 1968 US Election. Any close suggestions and tips to find something similar are much appreciated!

Thanks.


Califunkia  Sugerida por donshottype 
Espresso  Sugerida por donshottype 
Ravie  Sugerida por donshottype 

Psychedelic style of lettering too complex for a font, even with ligatures.
Some of the flavor of the style is shown in fonts like Espresso, but note that THIS IS NOT THE FONT.

If you have Microsoft Office 2007 or later, you have access to a font with this style, called Ravie, but note that THIS IS NOT THE FONT.

Califunkia, but note that THIS IS NOT THE FONT.
Other fonts in this vein include Baileywick Curly, P22 Festiva, Fantini, Scary Scrimshaw NF, Elephant Bells, ITC Ziggy, and Periwinkle Fancy.
