In looking at what other Historical Societies celebrate, I came across the notice that the Goleta Valley Historical Society is having a special exhibit of “‘Avenge Ellwood!’: The Japanese Attack on California,” a special exhibition commemorating the 70th anniversary of the Ellwood Shelling in Goleta. On Feb. 23, 1942, a large Japanese submarine identified as the I-17 surfaced at sundown off of Ellwood Mesa and fired its deck cannon at the tidelands oil-production facilities clustered along the shore.
Back in 2009 I did a post on this attack on California
The "Avenge Ellwood" logo was created in early 1943 for a war bond drive led by the 4th Santa Barbara War Savings Committee and the American Women's Voluntary Services. The image was used in newspapers, posters, and by local businesses who had donated to the cause. The money raised went directly to the purchase of a bomber plane and fighter plane that would boast the names"Flying Santa Barbaran" and "Ellwood Avenger." Like many WWII propaganda posters, the artist is unknown and the image was not copyrighted.
