The Mexican Museum in San Francisco offers access to more than 12,000 art objects that represent Mexican art and culture. Objects date back thousands of years and are an example of the role Mexican culture has played in the development of the country. The museum's permanent collection is its most important asset. The collection is divided into five different categories including Modern and Contemporary Mexican and Latino, Pre-Conquest, Colonial, Popular, and Chicano Art. In addition to the traditional art pieces, the collection also includes a variety of rare books and a collection of Latin American art that continues to grow. The museum offers a variety of educational programs that enrich the community and share the history and experiences of Mexican Americans. The museum focuses on educating and including the community in its programs and many of its initiative are " grounded in the concept of first-voice programming." The museum has hosted a Family Day program since 1990 and offers free admission to Bay area kids and adults. There are also a variety of creative experiences and hands-on activities that reach out to the Latino community, as well as those who wish to learn more about the history of Latino arts. The intention of family day is to involve and strengthen families, and to celebrate heritage, through art including mask-making, jewelry design, dance and storytelling presentations, music, and creating Trees of Life.
