Is 1991 Vintage for a Female Back Tattoo?

Germs Manager Nicole's Back (tattoo by Jill Jordan, photo by Sebastian), originally uploaded by N.Panter.Taken in 1991 for a Tattooed Women calender this female back tattoo combines sharp angles with swirls. It's the sharp angles that jump out at me, especially how the tattoo converges from both arms down to the small of her back. On another note, I must apologize for my lengthy absence.
