This short ten minute film recently posted to YouTube by BullDog Tours is entitled “City of Proud Memories”. Be prepared that it shows its age in some of the story telling and terminology used, but it is a fantastic glimpse into the city over 75 years ago. Of course what I am really partial to is the first scene which shows a trolley in motion on Broad Street. Later on there are further glimpses of the overhead wires for the trolleys, but that first scene is the only actual depiction of them.
And, if you are into this kind of picture into the past, as I hope you are, check out The Great Depression & World War II on the StudySC site. An amazing source of information in all formats.
