While the caption says this:
"Architectural rendering for new San Francisco Safeway store. Credit: Allen, Peter. “A Space for Living: Region and Nature in the San Francisco Bay Area, 1939-1969.” Dissertation, University of California, Berkeley, 2009. http://www.slideshare.net/pepepedro99/a ... -full-diss."
I'm inclined to think this wasn't region-specific, or might be for a different store in the area (i.e. one of the marina stores in Berkeley, specifically the one on Shattuck).
Are there other examples of blueprint/concept sketches that exist for this iconic design?
