From boo-hooray.com: “…inspired by Walasse Ting’s and Sam Francis’s publication One Cent Life, [Dutch artist and graphic designer Jacqueline de Jong] decided to create a salon-exhibition-style issue of The Situationist Times, featuring 33 artists who each contributed a lithograph (the motive was to raise money for subsequent issues). Issue 6 was launched in the spring of 1967 with two exhibitions in Paris at the bookshops La Hune and Le Divan.”
