Horses by Carlos Atoche, 2015
This Chilean born artist (1984), with an Argentinian mother and a Peruvian father, has interesting street art all over the city of Rome. These horses are "grazing" on the side of Via Prenestina, a short distance outside Porta Maggiore. (Note: This mural was painted after my 2014 Advent Calendar was posted!)
This is another horse by Atoche in Pignetto.
