The work starts near his shoulder, with a traditional-style pin-up girl straddling a rocket in an outer space motif:
The cat perched on the rocket in front of the woman represents Phoenix's love of animals.
The centerpiece of the sleeve, however, is lower on the arm and represents his love of astrology:
From a practical purpose, he had his natal astrological chart wrapping around his limb. In theory, he told me, anyone who knows astrology could come up and read his arm and gain insight into his astrological makeup.
Phoenix was born with the Sun in Aries rising in Leo and with his moon in Gemini.
This work was done by Lou at Third Eye Tattoo in Park Slope, Brooklyn, about six years ago. Lou's handiwork has been featured many times over the years here on the site and can be seen here.
Thanks to Phoenix for sharing his spectacular sleeve with us here on Tattoosday!
