Student seeks people who saw Haring chalk drawings in NYC subways in the '80s

I am a grad student at CSU, Chico working on a thesis on Keith Haring's chalk drawings created in the subway systems of NYC during the early 1980s.  If you saw these drawings in a the subways I would love to hear from you.  

I am conducting interviews with people about their experience seeing the pieces. If you would like to participate can send you an information packet that has more details.

Thanks for contacting me
