Original handbill (February 1967). Printed in purple and black on pinkish twiltone stock. 28x21.5cm. Reproduces a wildly hand-drawn text, the words 'Invisible Circus' and 'Free' in large purple-coloured lettering, with the remainder in black. A last-minute, pre-event handbill printed on the Com/co Gestetners upstairs at the Glide Church, mentioning "The John Dillenger Computor" (sic) along with the Artists' Liberation Front, Lion Priests and the Wind Spinners. Fine.
