Original 1st printing 11&1/8 x 17&3/8" concert poster for UK folk revivalists the Incredible String Band appearing at Jordan Hall in Boston, MA on 12/7/1968.

 Designer unknown/not credited (possibly Bob Driscoll), medium flat index stock poster is in beautiful near mint (A-) condition; just a touch of light ink spread across the lower margin, a softy pinch bend or two and a couple of hairline thin diagonal corner bends, otherwise it is an absolutely unbeatable example of this late-'68 ISB poster from Jordan Hall (show was promoted by the Boston Tea Party).
