Original 1st printing 10&7/8 x 17" concert poster for UK folk revivalists the Incredible String Band appearing at the Boston Tea Party (15 Lansdowne St location) in Boston, MA on 11/23/1969. Design by Bob Driscoll, medium flat index stock poster is in very good (B/B+) condition; a set of pin holes (all four corners), a 3/4" tear in the bottom left margin, a minor amount of edge/corner creasing and light handling, otherwise fine. Very quaint-looking late '69 ISB poster with a nice photo of Robin & Mike.
