LUTHER'S TOOL GRINDERS. LUTHER GRINDER MFG. CO., MILWAUKEE, WISCONSIN, U.S.A. c1920.
Featuring one of the best catalog covers ever, this small catalog is a perfect example of one company's use of paper advertising to tell the world that they had moved into the modern machine age. Great Arte Deco design. Take a close look and you can see the sparks flying from the grinding wheel. Quite a cover for something so mundane as a grinder.
