Numbers 1-9 (1) 1983

"Numbers 1-9 (1)," created in 1983, is a minimalist work by American Pop artist Robert Indiana. The piece features two simple, solid-colored shapes, a blue curve and an orange semicircle, that together form a powerful, eye-catching composition. This work is a signature example of Indiana's bold, geometric style, which was inspired by the aesthetic of advertising and commercial art.
