Handle with Care: 1936:
By the mid-1930s, the US parcel post system was more than 20 years old. It had opened a new world to rural Americans. Products that rarely left cities only a few years earlier now appeared at their doorsteps. And farm produce traveled to urban markets by mail.
Businesses depended on the efficiency, reliability, and security of the parcel post. A parcel that arrived late was sometimes no better than one damaged or lost.
