Black Sparrow Press is iconic, started by John Martin of Santa Rosa in 1966 -- years ago I bought a collection of Bukowski's poems and was so impressed by the book design that I searched out their books by George Oppen, William Everson, Diane Wakoski and of course more Bukowski. I have recently learned that the best-known book designer there was Barbara Martin and the exceptional typography was by Graham Mackintosh. Sadly Black Sparrow shut down years ago (2002 I think). Though you can still purchase items from the backlist.
I might also add, the title of the above poetry collection is one of my all time favorites. I doubt many publishers would encourage such a long title these days.
