UNTITLED (ENGLES PRODUCTS). 1966. SIGNED ON THE COVER BY ENGELS

Amsterdam: s.p. (Engles in association with Galerie A), 1966
30 x 10.5cm, 6pp plus specially folded card covers. Artist’s book designed by Engles which displays his conceptual items for sale. Here the cover is creased deliberately in a diagonal (as issued) so it can fold down to allow the inside of the book to be seen immediately. The second page is similarly creased to allow further exposure. This copy is signed in pencil on the front yellow covers above the fold. The edition size of this publication is not known but it is a scarce period conceptual work made more so by the uncalled for signature. Very good.
