Bay seniors who were knocked out by the deYoung’s recent Diebenkorn exhibit have a chance for second helpings of this remarkable artist’s work at the College of Marin in Kentfield now through Nov 14. Expect none of the mobs of the city show. It’s a considerably more intimate exhibit, just 40 pieces 38 of which have never previously been on public view. It includes many sketches, done while he lived in Berkeley and Healdsburg, the kind that opened our eyes recently to what a brilliant master of line work he was. Free.
