My sister came up big (thanks!) at the Ft Greene Flea Market, scoring two copies of this Picasso issue of Ralph Ginzburg and Herb Lubalin's Avant Garde magazine. Only lasting 16 issues, from '68 to '71, Avant Garde was amazing on so many levels-- not only for the design, but for its radical content. It also spawned the very famous typeface of the same name by Mr. Lubalin.
