Two students graduating from San Francisco State Normal School. During the "Ritual of the Teachers' Guild Service," graduating students wore robes trimmed with a sash and trim in the original school colors of green and gold. President Frederic Lister Burk developed the Ritual as Normal School's commencement exercise in 1909 and it was performed annually for 20 years, so that future teachers could consecrate their commitment to the teaching profession prior to entering the profession.
