Miguel was good to his word and e-mailed me the following photo:
Miguel told me that, one night, a couple of years ago, during a difficult time in his life, he had a dream about the tattoo and, when he awoke, he drew up the image he had seen in his mind. The vision, to him, "represents the evil that people have inside". He took the idea to Sunset Tattoo in Brooklyn, and one of the artists created the piece.
Thanks to Miguel for sharing his tattoo with us here on Tattoosday!
