I went to Taos (Sept 30) to see the frescoes in the old courthouse on the plaza, upstairs in the back room. However, this room apparently is always locked up. Therefore, I took the best photos that I could through the windows (perhaps the murals are easier to see in this YouTube video):
In addition to those WPA artists mentioned above, I believe that Frederico Vigil recently painted the fresco shown obliquely on the far right, in the below photo (on that same wall, there seems to be another rectangle reserved for a future fresco):
Fresco is inherently architectural. I thought the local Taos Earthships could encourage a fresco revival, on their adobe walls.
