Anatomia del Corpo Humano
A viewer recently submitted this incredible arm tattoo on one of her students at City College of San Francisco.
Looks like it's based on Juan Valverde de Amusco's Anatomia del corpo humano, which was most likely originally drawn by Gaspar Becerra (1520?-1568?), a contemporary of Michelangelo.
