This glass mural originally hung in the San Francisco Steinhart Aquarium Entrance, but now it is hung in the aquarium's kitchen hallway, in the bowels of the "backstage" area. I took the photo on my VIP tour summer. the card reads: VENETIAN TILE MURAL, Guillermo W. Granizo (1923-1997)
I really like this one. The colors of the glass tiles give it a deep transparency. Nice flow and movement.
