Ladies who went to the restroom to "powder their nose" in 1926 really were powdering their noses.  The sudden popularity of makeup for women at the turn of the century meant every would-be flapper had the essentials in her beaded purse:  lipstick, mascara, eyebrow pencils and face powder.
 
Ladies might have chosen Sarah Winn Face Powder, manufactured by the Kurz Chemical Company.  After all, it was "on sale" for 46 cents.

Around the same time, Bowser-Morner was founded in 1911 as Kurz Chemical before being purchased by partners Raymond Bowser and Arnold Morner just 14 years later.  As is common in business, they named the company after themselves.

Thinly-veiled newspaper "articles" regarding this waterproof face powder touted its amazing features and benefits.  Clearly it was traded to writers in exchange for kind words.  Sarah Winn Face Powder 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."

But we don't really know the whole story.  

For reasons unknown to history, Sarah Winn Face Powder was a short-lived product line for Bowser-Morner.  Along with other failed products (metal polishes, waterless soaps, and perfumes) the Sarah Winn Face Powder was discontinued shortly after its debut.
