Aerial view postcard of downtown

Here's a 1976 or slightly later postcard showing the view from the air, looking west toward downtown Atlanta. We know it's '76 or later because that's the year the Peachtree Plaza hotel was completed. Does anyone have any details on the filmstrip mural painted on the side of a building, sort of near the middle of the photo? Thumbnails of many more aerial view postcards can be found here.
