This is an original Fillmore West postcard mailed to people who were on Bill Graham's mailing list in the late 1960's.  This particular card was mailed to Dr. Francis Rigney.  Francis Rigney was a doctor in the Department of Psychiatry at UCSF and was known as the psychiatrist to both the Beats and the Hippies.

Doctor Rigney is actually mentioned by Tom Wolfe in The Electric Kool-Aid Acid Test.
