I visit the De Young Museum in Golden Gate Park every couple of months.
Mostly, I go to see just one exhibit, and focus on that.
I always, however, stop in to see the Piazzoni Murals: The Land and The Sea on the first floor. You don't need to buy a ticket to the museum to see them.
These are portions from two of the ten panels, from 1931, originally displayed in the San Francisco Public Library. They are associated with the Beaux-Art style.
