my favorite is, was, and will be Van Gogh but many of you've talked about him so i won't do it again, i would post Dali too, but you already did it, so...
i'll introduce you a peruvian painter (my favorite
peruvian painter) his name is Gerardo Chavez, he mix his elegant style with the energy of the traditional art of the old cultures what poblated peruvian territory so many years ago, the result is - in my opinion- just beautiful, this is one of his most popular paintings (my favorite is one called "The Boulevard", but i can't get an image on line
) this is called Mama
(mother), enjoy it:
