December 16, 1963. Fire destroys the old gymnasium at the College of Marin in Kentfield, California. Arson suspected. The building had already been condemned for public assembly and was scheduled for demolition. In a way, the beginning of the end of the mission revival architecture of this institution, of which nothing remains on the present campus. Also: 1960 Thunderbird; vintage Van Pelt fire engine, but I can't identify the original truck make. Plus a really vintage, even for 1963, pedestrian signal at the extreme left. 35mm Kodachrome.

April 21, 1955. Using the self-timer on his new Lordox 35mm camera and a roll of high-speed Kodak Tri-X film, my brother photographed himself in what appears to be the canned soup and dog food section of the Rainbow Market, the exterior of which can be seen here. View full size.
