Edgar Lee Hewett, an anthropologist involved in supervising the nearby Frijoles Canyon excavations (now
Bandelier National Monument) was instrumental in developing the careers of several San Ildefonso "self taught" artists including Tonita Peña. Hewett purchased Peña's paintings for the Museum of New Mexico and supplied her with quality paint and paper. Peña began gaining more notoriety by the end of the 1910s selling an increasing amount to her work to collectors and the
La Fonda Hotel. Much of this early work was done of Pueblo cultural subject matter, in a style inspired by historic Native American works, however her use of an
artists easel and Western painting mediums gained her acceptance among her European-American contemporaries in the art world. At the age of 25, she exhibited her work at museums and galleries in the Santa Fe and Albuquerque area. In the early 1920s Tonita did not know how much her painting sold for at the Museum of New Mexico, so she wrote letters to the administrators because a local farmer was worried that she got paid too little. In the 1930s Peña was an instructor at the
Santa Fe Indian School and at the Albuquerque Indian School As children, these artists attended San Ildefonso day school which was part of the institution of the
Dawes Act of 1887, designed to indoctrinate and assimilate Native American children into mainstream American society. Works from this exhibition were shown at the 1932
Venice Biennial. That year is the only time
Native American artists have shown in the official United States pavilion at that biennial, and Tonita Peña's paintings were part of that exhibition. Her painting
Basket Dance, that had shown in the Venice Biennial was acquired by the
Whitney Museum of American Art in New York for $225. This was the highest price paid up to this time for a Pueblo painting and most Native American paintings at this time were selling between $2 and $25. == Death and legacy ==
