California Crazy: Roadside Vervancular Architecture was compiled by Jim Heimann and Rip Georges in 1980. Unfortunately much of what you see here no longer exists today.
From the back of the book:
“California Crazy is the style of architecture that seems to typify California itself: naive, direct, unpretentious. These buildings were designed to catch the eye, to be remembered. No ad agency conceived them – they were often designed by the owners themselves, poured of ferro concrete and shaped by the undisguised desire to sell.”
