This is the Studebaker Commander Business Coupe. The car had a large truck for the transportation of inventory by the traveling salesman. If merchandise was not on board the cargo area could be used for luggage. In the era of this automobile the country would have been much more sparsely populated than it is today. This would require the salesman to travel great distances and carry much of his wares along on the trip. It might have been common for the salesman to start out with a full load and make a circuitous route to sell his goods before returning to his starting point.
