Large paper poster with a montage of four photos of John Buttner with President John F. Kennedy, circa 1962.  29 1/2 x 45", in excellent condition.  Inscription bottom right: JOHN F. BUTTNER  15 GREW HILL RD.  ROSLINDALE, MASS.  Kennedy and Buttner were both from Massachusetts, and both were Navy veterans.  It's possible that these were displayed in VFW halls.  This is the only example of this poster we've ever seen.  Extremely rare.
