On Twitter, @DigitizingStl posts historic public documents that relate to St. Louis. He recently posted aerial photos in the Brentwood, Maplewood and Richmond Heights areas that show the effects of development 1937 – 2015. Neighborhoods disappear, city dumps become retail areas.
The historical aerial photos are from the St. Louis County website.
