Frank H. Atkinson was a popular Art Nouveau sign painter in Chicago, Illinois. He designed signs for the Cadillac Motor Car Co., Chicago Academy of Fine Arts and the department store Marshall Field.

Oddly enough, he even designed signs for other sign painters.

In 1908 he published a book, Sign Painting, which sold well.

French Plug, a bold, rounded, all-cap design in an American Art Nouveau style from that book. It has a relaxed, easy-going informality that is useful for ads and flyers. It also would have fit very nicely with many French posters of the period.
