The journal More Business “The voice of letter press printing and photoengraving” was produced from 1936-42.Louis Flader was the publisher. Flader’s legacy is having edited the comprehensive Achievements in Photo-Engraving and Letter-Press Printing (1927), a massive volume featuring step-by-step explanations of engraving processes and hundreds of full-color illustrations and photographs by over 350 photoengravers.
This is an amazing publication. It shows some wonderful layouts. Considering that these techniques were achieved without tools like Photoshop. I recently acquired a couple of issues. Here is April 1942.
