This is a mural I did for the Gonzalez family. My sister-in-law, Gloria, wanted me to match the color scheme of the rest of the room. You can see that scheme in the top picture, to the extreme left. This is actually two murals. The one on the left is an Arizona landscape, and the one on the right is perhaps a Sonoran Desert scene. It is a desert in Mexico because you can see Speedy Gonzales on the far right. But, on second thought, after looking at some pictures of the Sonoran Desert, this is probably the Sahara Desert. And why is Speedy Gonzales in the Sahara Desert? Because he is fast.
