Gustavo Bacarisas y Podestá was a Gibraltarian painter based in Seville and author of the poster of the Ibero-American Exhibition painted in 1928. The poster arranges an allegory of Spain surrounded by those of the American Republics, and behind them the Plaza de España with its two towers along with the Giralda of Seville in the center of the composition. It was topped with a halo of the flags of the participating nations. 

 

His work for the Exhibition was very important. He designed the ceramic panels for the Royal Pavilion of the Plaza de América and painted a series of large format twigs (paintings on cotton cloth) that passed to the Royal Alcazar of Seville at the closing of the Exhibition. 

​

He also painted the ceramics of the court for the Pavilion of Argentina and the Palace of Industries, where he also created the tempera paints for the drum of the dome.
