I very much like these Ghetto Fridas by Chicano artist/activist Rio Yañez. His interviews with Ghetto Frida here, here, and here are also worth reading. They're really funny, but also very informed. He also has a (small, at this point) series of Chicano icons as zombies, which is pretty awesome, and some other things that are probably only of interest to the Mexican segment of my readership (which is actually significant because not very many people read this, and at least two of them are Mexican (sup Molly, sup Dave)).
