Joseph Beuys' "Noiseless Blackboard Eraser" is a conceptual multiple from 1974 that transforms an ordinary felt eraser into an artwork by presenting it as a signed, numbered edition enclosed in a Perspex box. The work exemplifies Beuys' interest in elevating everyday functional objects into aesthetic and philosophical statements, questioning the nature of art production and the artist's hand through mass production and duplication. Published by Ronald Feldman Fine Arts in an edition of 550, this 3D multiple challenges conventional notions of originality and authorship while maintaining the artist's signature authority through labeling and numbering.
