the work "The Natural Riches of Brazil", created by Vantuir Gonçalves Gomes, is a recreation of the flag of the Federative Republic of Brazil. Officially presented on November 19, 1889, the Brazilian flag has three main colors: green, yellow and blue. Each color has a special meaning for the history of the Brazilian nation. The green color represents the Brazilian woods and forests. The Amazon is a great example of Brazil's rich ecological reserves. The yellow color represents our numerous reserves of gold and precious stones. Finally, the blue color represents our sky and our rivers. The 27 stars represent the 27 Brazilian states. The planes and the ship represent Brazil's technological development. The green color so wide in the painting represents environmental preservation.
