Macklin Grinding Wheels: Protect your Production (cover title)

Softcover 4to, [20]pp. Outer wrap for supplement "American Engineering Standards Safety Code" for 1930 stapled inside rear wrap (no contents to the supplement and not called for with the publication). Ice blue metallic wraps. Very Good with creasing toward the upper edge of the tall volume, middle 4 leaves with abrasion toward at the bottom of the spine. Unusually and predominantly graphic, the individual pages were also reproduced as standalone ads in other publications and are remarkable for their strong graphic appeal and repeating elements of branding, specimen illustrations, and photos of workers using the products.
