At 5:27-5:35 time marker in the 50's video is the The 1939 Streamline Moderne style May Company Wilshire building in Los Angeles that is captured but only the bottom floor.
It was later adapted for use as The Academy Museum of Motion Pictures
(Above descriptions from Wiki)
I saw the May Company appliance store in the video and wondered if was affiliated with the May Company we had around Cleveland. It was, although different May family members ran the regional businesses, all reported into the parent May Co.
