This interesting image is of Southdown Queen Mary 954CUF well away from home turf as a mobile exhibition for holidays in Sussex. Seen here in the mist at Leeds next to a board showing how many people have been killed this month!
Thanks to everyone for the location help, its Eastgate in the city centre. The building in the background still exists.
Medium format neg. Undated but the bus was delivered 1964 so circa 1964/65.
