This is an original, first printing (there were no reprints) of Victor Moscoso's "CLEAN-IN." The poster publicized a "spring mobilization" to clean up the "Haight Ashbury neighborhood." The Clean-In was held on January 22, 1967, one week after the famous "be-in." The poster is in near mint condition. Colors are bright. 14" x 20". This is a fantastic poster to add to your collection.
