Hagenbeck-Wallace Circus early 1920's #3

Cap Curtis' canvas spool being unloaded by a team of horses and it was rewound by a gasoline engine mounted on ther rear. As you can see this method, tho saving time and labor, was very hard on the canvas being dragged back and forth across the lot every day and was eventually discontinued. As we know today's spools load and off load from the rear enabling the vehicle to move toward and away from the canvas.
