Here are two rare cause buttons, the only one’s we’ve seen, with Levin’s documentation on the reverse. On the 1974 curl dated 3.5” “Free Olga”, Levin’s reverse note reads “Talamantez (Argentina)”. She is a U.S. citizen, Chicana political activist and current executive director of the California based Chicana/Latina Foundation. At the Univ. of Calif. , she earned her degree in Latin American Studies and in the 1970s went to Argentina to work for a poverty relief agency. In Nov. 1974, she was arrested for political activity, imprisoned and tortured. The Olga Talamante Defense Committee petitioned Congress and the State Dept. for her release. She became nationally known and was freed March 27, 1976. Second 2.25” button has grease pencil back note “Lat. Am.” Mark Curtis was a union activist in 1988 defending 17 coworkers from Mexico and El Salvador who were arrested in an immigration raid at the Swift meatpacking plant in Des Moines. He was arrested on false (according to the Socialist Workers party) charges of rape and burglary. He was released from prison in August, 1996. Both buttons are mint and come with Hake’s COA.
