String-and-Ball Trick

A clipping. This actually has something on the reverse, and judging by the paper, I was guessing it came from a magazine. With a little googling of the author's name, I found a reference via ChestofBooks.com. It looks like it appeared in an actual book: The Boy Mechanic Vol. 2 1000 Things for Boys to Do. There was a 1914 edition, and a 1940 edition, but I am unsure which edition this was cut from. If it was the 1914 edition, this collection could be a bit older than I originally thought!
