Two artist's books by the pioneering Swiss-German Fluxus artist Dieter Roth, each bearing his distinctive hand-applied signatures and numbering — one boldly marked in blue paint, the other in pencil — affirming their place within strictly limited editions of 100. The works reflect Roth's enduring fascination with the book as both artistic object and intimate record, where the act of signing becomes an extension of the creative process itself. Dated 1973, these volumes exemplify his radical approach to multiples, blurring the boundaries between mass reproduction and singular, hand-touched authenticity.
