One of those paintings, signed “Sarah Honn” and dated “May 5, 1866 AD,” imitates the American primitive folk art style and is entitled , (Fig. The painting was seized by the US Federal Bureau of Investigation.

This case study was thoroughly investigated previously and numerous telltale signs of forgery were identified (23).

It is only possible nowadays thanks to technological advances of the 21st century that have made the technique viable for application to microsamples.

The case study presented here is a known forgery created by Robert Trotter (b. By his own admission, Trotter conducted 52 sales of his fakes and forgeries from 1981 to 1988 (23).

This approach provides relative age information only and thus may fail in proving a forgery.

Radiocarbon (C) dating is an attractive alternative, as it delivers absolute ages with a definite time frame for the materials used.

Radiocarbon dating has the potential to answer the question of when an artwork was created, by providing a time frame of the material used.

Art forgeries have existed since antiquity, but with the recent rapidly expanding commercialization of art, the approach to art authentication has demanded increasingly sophisticated detection schemes.

So far, the most conclusive criterion in the field of counterfeit detection is the scientific proof of material anachronisms.

The establishment of the earliest possible date of realization of a painting, called the , is based on the comparison of materials present in an artwork with information on their earliest date of discovery or production.

With the advent of accelerator mass spectrometry (AMS) (2, 3), the amount of carbon necessary for obtaining a radiocarbon date was significantly reduced from a few grams down to 1 milligram carbon (4).

Technical advances in general, and especially in the field of gas ion source AMS (5, 6), where mixtures of CO and He gas are introduced straight into the GIS-AMS, have reduced sample requirements to micrograms of material (7), thereby setting a new milestone.
