Melanie Cervantes is a 31-year old Xicana artist-activist from Los Angeles that is now based in Oakland, California. Cervantes views her art practice as a part of a growing movement for global social justice producing her work in various mediums including pen and ink, acrylic, screenprinting, and paper stencils. Employing vibrant colors and hand drawn illustrations her work moves those viewed as marginal to the center and features subjects such as empowered youth, elders, women, queers, indigenous people and communities of color. Cervantes often works in collaboration with grassroots organizations creating prints that address issues such as immigration, racism, indigenous autonomy and self-determination, revolutionary feminism, LGBTQ rights, the prison industrial complex and prints that call for international solidarity. As a member of the Taller Tupac Amaru she works to foster a resurgence in the screenprinted political poster. Following the tradition of such artists as the Taller Grafica Popular, the Organization of Solidarity of the People of Asia, Africa & Latin America (OSPAAL),Emory Douglas, Juana Alicia, Malaquias Montoya, Las Mujeres Muralistas, Judy Baza and Juan R. Fuentes –Cervantes has made a life long commitment to being an artist for the people.

highResolutionResistirEsSobrevivirIMG_7486Miriam Flores is a first-generation Latina college student attending the University of Utah pursuing a degree in Social Work. At an early age, Miriam was attracted to art due to inspiration from her uncle’s work. Her art explores contemporary issues in Utah and shows an ongoing effort to explore and imagine art that encompasses social justice. She portrays black and brown bodies and oppressed communities by centering them through different mediums of art, photography and/or graphic .design.Miriam states, “I have learned to not be ashamed in my lack of understanding of something or concepts being discussed within social justice. I have found that by asking questions and being outspoken about my desire to learn, I have been better able to articulate through my artwork. Art has allowed me to further explore what it means to be Latinx and be involved in marginalized communities.” The graphic, “Resister Es Sobrevivir” came about through the original focus for a statewide high school conference with the observation that media lacked womxn representation. The theme of resistance and indigenous roots was incorporated to the piece by the clothing, hair and fist in the air. The element of butterflies was included in effort to express migration and other political associations prevalent today such as DREAMERs.
