American Motor Truck Company showcased their four-ton truck (which had 30-36 HP from a four cylinder engine) at the 1906 Chicago Auto Show, with was held at the First Regiment Armory, once locate at the corner of Michigan Avenue and 16th Street in Chicago's Motor Row.

Except from a 1906 article in the 1906 isle of The Automobile.
Commercial automobiles occupied a good deal more space in the Chicago show than the average visitor realized, unless he was particularly interested in such machines, for the business vehicles were so scattered throughout the two buildings and, in most cases, so surrounded by the more ornate and outwardly attractive pleasure cars, that the "emancipator of the truck horse" was not particularly conspicuous. In New York the trucks and delivery wagons were kept together to a great extent, and their very appearance of unostentatious power and strength when massed lent a charm to the long rows of monsters which was absent from the isolated exhibits at the Chicago show.
