Untitled (Red, Black and Silver), 1956 purportedly the last known work of Jackson Pollock

This small poured painting, known as Red, Black and Silver, purportedly the last known work of Jackson Pollock, is one of the most famous – and controversial – in American art. It has never been viewed publicly, having been in the possession of Pollock’s former mistress, Ruth Kligman, from the time it was painted until her death in 2010. Although its provenance is remarkable, as well as unique – Kligman claimed she watched Pollock make it for her in July 1956, on the lawn outside his house in Springs, New York, and on top of a half-finished painting of her own – the Pollock Krasner Authentication Board deferred an official authentication of the work. Given the technical and scientific evidence that corroborated Kligman’s account, the motivations of the Board are largely suspected to be political. Since the dissolution of the Authentication Board in 1996, leaving no recognized authentication entity, the painting has existed in limbo.

Following Kligman’s death in 2010, the co-trustees of her estate renewed efforts to establish the truth about the painting, enlisting experts in art history, paint and chemical analysis, probability mathematics – and forensic science. In 2013, trace evidence found embedded in the paint was compared to that found on the property at Springs and in Pollock’s own shoes, finally and definitively proving the painting’s provenance.

This case not only demonstrates the challenges currently faced in the authentication of iconic works of art, but the successful use of coordinated scientific analysis, including forensic trace analysis, offers a viable course for authentication of art more widely.
