Begun in 2007, the Denied Warhol Series tackled issues of authorship, originality, and authenticity, in addition to art commerce through the work of Andy Warhol. Inspired by the then-recent turmoil created when The Andy Warhol Art Authentication Board rejected the authenticity of a high-profile "Warhol Self-Portrait," the artist replicated 12 identical "Warhol Self-Portraits" and then sent them to be formally marked DENIED by the Authentication Board. This act created new value from a process used to negate value, also calling authenticity into question. From those initial 12 paintings, the artist replicated the DENIED stamp of the Authentication Board and then created further works. He then imposed the DENIED mark himself, taking the concept even further. In 2011, the Warhol Art Authentication Board was disbanded.
