A retrospective featuring the first five canvases of the Slav Epic and a large selection of works by Mucha opened in January 1921 at the Brooklyn Museum in New York. The exhibition had already proved a resounding success in Chicago where it had attracted around 600,000 visitors, and it was met with equal enthusiasm by critics and members of the public.

The poster features a girl with Slav features and an abundance of undulating hair. She holds a circle of thorns and stars as a symbol of the past and future of the Slav people.

The poster captures his signature style and the patriotic subject matter of his later work.
