Zooming up to the post-war period, we come to the new-fangled, regional-class shopping hub, with its large, multi-story department stores and acres of free parking. In this snapshot is Von's (spelled with an apostrophe in 1947), which was a charter tenant at Los Angeles' BROADWAY-CRENSHAW CENTER.

Another innovative, post-war retail hub was ChiTown's PARK FOREST PLAZA. In this view, we see its Jewel Tea Company (or Jewel) supermarket, which opened in 1950. The store -and shopping center- were noteworthy at the time for having central air-conditioning.
