Soft cover. Condition: Good. First Edition First Printing. Part of a collection of books, prints, & "spatial projects--objects, construction boxes, etc." published by the Dutch Foundation "Octopus" Deventer to promote the Plastic Arts & the work of artists engaged in the pursuit of new possibilities in those arts. Profusely illustrated with the colorful "op-art" that emerged in this era, along with images from what look to be experimental theater productions, with many black-and-white photos (many featuring nudity). In 224 pages, lavishly illustrated on nearly every one. Originally issued inside a can (NOT PRESENT), this is a FIRST EDITION, First Printing from 1970 (no date in book). Quarto with colorful wrappers is in Good condition, downgraded because of a cracked spine, though this is quite typical for this book. Most pages are loose or completely detached, though all are present. Very clean, pages white, colors bright. Very slight rubbing to extremities & corner bumping. SPINE IS CRACKED, CAN IS MISSING. Our photos depict the EXACT book you will receive from us--never "stock" images of books we don't actually have!
