This antique image from 1909 showcases a Diagram of Hiram Stevens Maxim Propeller Testing Machine. It is a unique piece of history that reflects the advancements made in the field of science and technology during that time.

We found this amongst a cache of clippings of antique cartoons, pictures, portraits, maps and other images from publications from the year 1909. That means the backside of the image may have another image or text.

Wear commensurate to age, including, possibly, chipping at edges, minor folds, and other minor issues. You get what you see :)
