This document discusses two interconnected events that occurred in 1956 celebrating the 50th anniversary. The first was the international recognition of Concrete Poetry produced by the Noigandres group of Brazilian poets. The second was the opening of the first National Exhibition of Concrete Art in São Paulo, which featured paintings, sculptures, and poster poems exhibited together. This helped establish the label "Concrete Art" in Brazil and linked visual artists with Concrete poets. The exhibition included works from the Ruptura and Frente groups and affirmed their view as the avant-garde in art and poetry.
