During the holiday season, we advertised A.C. Gilbert's No. 7 1/2 Motorized Erector set as a last-minute Christmas present. What boy wouldn't uphold "25 pounds of scientific thrills" as the world's greatest toy? As the illustration shows, this kit could actually produce hundreds of different steam shovels, ferries wheels, airships, automobiles, and more. The kit also came with a toy motor for additional realism.
