This striking work by Daniel Buren is crafted from aluminum, bearing the hallmark of American manufacturing with its "Made in USA" designation. True to Buren's signature conceptual practice, the work challenges traditional notions of art authentication and institutional validation, with the title itself—*This Work is Accompanied by a Certificate of Authenticity*—becoming an integral part of the piece's meaning. The use of industrial aluminum reflects Buren's long-standing engagement with the relationship between material, context, and the systems that define and legitimize art.
