Does the automobile in the lower left corner of this photo look like a 1955 Packard Caribbean Convertible?
I don't know where the original photo or the 'first scanned' digital file is located. I have seen various versions on the web.
I do know that this photo is of the 1956 Pegasus parade on Broadway in Louisville Ky.
The photo could have been taken from a upper window of the Brown Hotel at 4th and broadway, or maybe the courthouse top floor at 7th street looking west. But most likely if could have been taken from the top of the Courier Journal building.
