Earlier I mentioned Strawbridge & Clothier. Here is a link to photos of Christmas at department stores. Go to Nos. 20 and 21 to see Eighth and Market at its holiday height. And particularly appreciated is photo No. 12 of Miller & Rhoads in Richmond, Va. Hard to remember stores so huge (and oddly connected) that they had to point you to escalators and elevators. Hudson's in Detroit had local and express elevators. And, of course, the exits had the street name over them, because inside you had no idea where you were.
