Poster For The Harlem Better Business League

Round red, blue and off-white poster enclosing a smaller circular vignette of an African American family with the caption "A Clerk in Negro Business at Home. The Result of Group of Economy". This unusual poster was possibly meant to be hung at one's place of business. The design of the poster is intriguing - incorporating two circles, the smaller of which is within a square, bearing the motto "Trade on the Square", "For Better Standards of Living", "Buy within the Circle".
