Ladies who went to the restroom to "powder their nose" in 1926 really were powdering their noses.  The sudden popularity of makeup for women meant every would-be flapper had the essentials in her beaded purse:  lipstick, mascara, eyebrow pencils and face powder.
 
She might have chosen Sarah Winn Face Powder, manufactured by the Kurz Chemical Company.  After all, it was on sale for 46 cents. Bowser-Morner began in 1911 as Kurz Chemical before being purchased by partners Raymond Bowser and Arnold Morner in 1925.  As is common in business, they named the company after themselves.

Newspaper ads and articles regarding this waterproof face powder touted its amazing features and benefits.  It was "on the market in various cities of Indiana, Ohio and Kentucky during the past two months, and the demand for this powder has simply swamped the local plant," the Dayton Herald reported.

To meet the extraordinary demand for this face powder, the "entire work force of the Kurz Chemical Company has had to work continuously day and night during the past month."

Face powder manufacturing was short-lived for Bowser-Morner.  Along with metal polishes, waterless soaps, and perfumes, the Sarah Winn Face Powder was discontinued.
