[1][3] In 1943, Antonio M. Ruiz became director of La Esmeralda and Estrada moved on to become one of Frida Kahlo’s private students.

With this group, Estrada began mural painting, working on a wall of a pulque bar called La Rosita, which since has been destroyed.

[1][5] He has also created murals for the Museo de Arte Moderno, in various houses in Mexico City, in Oaxaca, Nuevo Laredo and San Luis Potosí.

[6] Since then, he has had individual and collective exhibitions in various venues in Mexico such as the Palacio de Bellas Artes, the Museo de Ciencia y Artes of UNAM as well as in countries such as the United States, China, Canada, Venezuela, Colombia, Bulgaria, Poland, Romania and the former USSR .

[1] However, he still continues to give classes at La Esmeralda as well as workshops in other places in Mexico such as the Universidad de Colima.

[8] Estrada describes his work as a “mixture of the popular and the hidden.”[6] He is known for the use of a wide variety of bright colors,[5] and his style mixes elements of traditional Mexican folklore, typical scenery of the country, flowers and fruit.

[1] His 2011 exhibition had works which experimented with elements of impressionism, neo-impressionism, constructivism and surrealism, while maintaining social themes.
