I agree. I think it's just a row of pot plants with the largest on the right. I may be wrong, but the window appears to be closed.

I managed to find a picture of Nancy's at the 6340 Hollywood address. LAPL don't date this image, but
waterandpower.org have decided that it's circa 1940. On the right, the store that had been/would become (?) Nancy's is called Dinel's. I couldn't find it in the CDs, but the window display suggests that it also sold women's clothes. The picture also shows Thrifty, the Hollywood Beauty College, Schwabs, Western Union and the Hollywood Citizen Stationery Store.
