During the 1950s, the 'Science of Selling' became a cornerstone of the American Dream, leading corporations to invest heavily in visual aids to professionalize their workforce.
Maker / Origin
The signature 'COULTER' belongs to a commercial illustrator active in the mid-20th century, likely working for a major educational or corporate publisher like The Dartnell Corporation.

The posters show visible horizontal fold lines, which is common for ephemera that was originally mailed in flat kits. There is minor edge wear and some slight ink transfer, but the colors remain exceptionally bright and have not suffered from UV fading.
