Barbara Stauffacher Solomon: Why? Why Not? at YBCA brings together the designer, artist, writer and landscape theorist's full practice for the first time since her death, from the 1966 Supergraphics at The Sea Ranch to her 1992 book Good Mourning California. Drawing on her estate's archive and a new Supergraphic on YBCA's walls, it travels from Swiss grids to California freeways.
