San Luis Obispo

"San Luis Obispo is a city in California, located roughly midway between San Francisco and Los Angeles on the Central Coast. The city, referred to locally as SLO or "San Luis," is the county seat of San Luis Obispo County and is adjacent to California Polytechnic State University (Cal Poly). As of the 2000 census, the city population was 44,174." - from Wikipedia:,_California.

Brief history:
"The City of San Luis Obispo serves as the commercial, governmental and cultural hub of California's Central Coast. One of California's oldest communities, it began with the founding of Mission San Luis Obispo de Tolosa in 1772 by Father Junípero Serra as the fifth mission in the California chain of 21 missions. The mission was named after Saint Louis, a 13th Century Bishop of Toulouse, France. (San Luis Obispo is Spanish for "St. Louis, the Bishop".) It was first incorporated in 1856 as a General Law City, and became a Charter City in 1876." - from municipal website:

The municipal seal consists of the standard circular format. The background color of the outer ring is dark blue with gold external and internal bordering. At the top of the outer ring are the words 'CITY OF' and at the bottom 'SAN LUIS OBISPO' in gold block lettering. At the 10 and 2 o'clock positions respectively are two small gold five-pointed stars. The central image is that of Mission San Luis Obispo itself. The structure is white, representing its stucco construction, with chocolate trim and gray archways and windows. Above the mission building is a robin's egg blue sky, while in the left foreground is a tree proper. The right foreground contains a flowering hedge in dark green with multicolored small flowers on a green lawn.

An e-mail to the Office of the City Clerk elicited a response from the Deputy City Clerk which stated that while there is no official flag, the thumbnail of the design which appears on the Home Page of the web site is generally considered to be the city flag. She drew my attention to the municipal seal which appears on other pages of the web site, but did not indicate whether this was also used as a flag or not.
