Tineo's art has been profoundly influenced by the social, political and historical issues pertaining to Mexican-American identity in America.
Chicano Movement The rise and political development of the
Chicano Movement in the 1960s and 1970s, and concomitant birth of the
Chicano Art Movement, helped focus Tineo's attention on the role of art in community activism. During this period Tineo spent time working with the
Brown Berets,
MEChA (Movimiento Estudiantil Chicano de Aztlan) and other community activist groups, and he is still considered one of the most influential leaders of the
Chicano Mural Movement in Arizona. Decades later, in 1991, Tineo's art was included in the
Chicano Art: Resistance and Affirmation (CARA), exhibit organized by the Wight Art Gallery in
UCLA. The CARA exhibit, which traveled to various cities around the U.S., was the first exhibit ever to focus on the works of artists engaged in the Chicano civil rights movement; it firmly established
Chicano art – in all its forms – as a distinct and legitimate part of American Art in general.
Clifton miners' strike Tineo's artwork first came to national prominence after the 1983-1986
Arizona Copper Mine Strike in
Clifton, Arizona, which pitted local union workers – most of whom were Hispanic—against the
Phelps-Dodge Corporation. Tineo was asked by union leader Angel Rodriguez to come to Clifton and paint a mural that would symbolize the union workers’ plight and the essence of their struggle. Because tensions were high during this multi-year strike –- at one point the National Guard was called in, as well as a virtual army of state policemen backed up by tanks and helicopters -– the event drew international media coverage, and Tineo's mural has frequently been used as a visual representation of the pivotal point in U.S. history when the power of America's unions began to decline. Tineo's 10’ x 40’ mural still graces the inner north wall of the former Steelworkers Union Hall in Clifton, and the image has been used on banners, posters and signs to commemorate the episode. == Artwork ==
