Postcard photo of the <a href="https://en.wikipedia.org/wiki/en:Rexall_Train#Rexall_Train" class="extiw" title="w:en:Rexall Train">Rexall Train</a> which traveled North America in 1936.  Rexall was a chain of pharmacies in the United States and Canada.  Since the effects of the Depression were still being felt by many people, the company's president had an idea to have a traveling Rexall convention instead of the traditional meeting in one place, which would save the attendees travel expenses. The train's stops were where its local conventions would meet; the public could tour the 12 car train, which had displays of Rexall products as well as meeting areas via a free ticket from a local Rexall store.  The train was leased from the New York Central Railroad and its locomotive was a streamlined 4-8-2 "Mohawk" type.
