I really love when I found slides from travellers. They always show some interesting pictures of public places in a more relaxed way than taken by locals, since tourists always have a different way of portraying the city.
This slide from december 1970 shows a commom everyday scene of Philadelphia. And for many people not be worth a photo, but worth to these three people: one stop to eat some pretzels.
Two different views from the same crossroad in 1955 and nowadays at Philadelphia
Not many changes in this view in the last 58 years, all the buildings remains the same. The stores are a little different from 1955 to now and we can notice this corner of the city looks like is pretty quiet until today.
