I am 41, grew up in Philly. "Di-Dee" Diaper service for cloth diapers, milkman, Charley's Chips - pretzels and chips in tins that were returned/reused. Hucksters - that dang pa system; "Jerseee toe-may-toes, 3 lbs for a doll-lar", Schmidt's brewery in the hood, that's where your beer came from in those returnables. Frank's, local sodas in returnable bottles.
All your cousins lived within walking distance so you could easily get to all those "hammidowns". And yes, we all did walk to school and we walked home for lunch made by Mom -you knew when it was noon when the 12 o'clock whistle blew.
"Di-Dee" Diaper service" it's Nu Di Diaper service with the blue and pink trucks with the white letters.
The milk man would put the milk on the front porch in a metal box that would hold 4 quart glass bottles.
Back in the day, you could almost fix your own TV by going down to the local TV/radio shop and test the tubes, I remember it well watching my dad test the tubes at the store.
I remember collecting the tin soda cans and news papers very well.
