The Colegio César Chávez Collection consists of materials that were collected by Arthur and Karen Olivo and their son Andrew Parodi. The materials include publications, correspondence, a bilingual college catalog, a Mount Angel College Yearbook, and photographs. The photographs depict the time period in which the Olivo and Parodi family lived on the grounds of the college campus. They include photographs of the campus; the Olivo and Parodi family gatherings on the campus grounds; and a poetry reading by the Chicano poet and activist Alurista (Alberto Baltazar Urista Heredia) at the Colegio.
The collection also includes a 1980 letter to Arthur Olivo from Oregon Governor Victor Atiyeh and a certificate documenting Olivo's appointment to the Oregon Occupational Information Coordinating Committee. A 1980 photograph of Olivo, Governor Atiyeh, and others (probably members of the Committee) is also part of the collection.
In addition, the collection also includes two large posters, one by the artist Desiga, and another, a recruitment poster, by the artist Carlos Manriquez. Manriquez is also the artist of a 1979 Colegio calendar. The calendar, consisting of four sheets plus a cover sheet, includes a timeline of significant events in Chicano history along with full color imagery depicting “jalapeño power.”
