The Three Amigos Market Mural is located on the side of Three Amigos Market at 1554 13th Ave at the weird intersection of Foothill, 13th Ave and 14th Ave. The mural features a jungle scene with a hummingbird, a gorilla, a frog and a sunset over an ocean.
There is also a weird sign/former mural on the other side.
As of February, 2020, both of these murals have been replaced. http://oaklandmurals.com/?p=2584
