You may or may not know that AMPAS (Academy of Motion Picture Arts & Sciences) is in the process of turning the May Company building on Fairfax and Wilshire into their new motion picture museum. It's about two years away from opening.

Among other things, on their site they have a link to the museum with drawings and renderings and a section devoted to the May Company building with a lot of photographs and a magazine article from the May 1940 edition of The Architectural Forum, detailing the building and it's floors. Most of the photos are from the 1940's.
I don't believe this photograph to have been posted here before.

It's an aerial of the May Company from 1940. You can see Simon's on the corner of Fairfax and Wilshire, too.
