Hear about William Henry Ireland's fake manuscripts of William Shakespeare including a letter written to his wife — Forgery A look at a letter supposedly written by William Shakespeare to his wife, Anne Hathaway; it was, in fact, faked by William-Henry Ireland.

In the context of art, forgery is defined by an "intent to deceive," and the methods used to create these fraudulent works vary significantly in their approach and difficulty of detection.1

Exact-Copy Forgery

An exact-copy forgery involves creating a duplicate of an existing, genuine work of art. This is generally considered the easiest type of forgery to produce and, consequently, the easiest to detect. When a duplicate appears, the primary challenge for experts is simply determining which object is the original and which is the copy. Detection often relies on comparing the suspected piece against the original to identify inconsistencies in materials, aging, or composition.123

Stylistic Forgery

A stylistic forgery is a work created "in the style" of a specific artist or historical period and then presented with a deliberately false attribution. Unlike an exact copy, this method does not replicate a single known piece but instead mimics the unique flair, techniques, and conventions of an artist or era.132

This is considered the most difficult type of forgery to detect because it requires the forger to possess a deep understanding of the artist's attitudes and methods. Because these works are presented as "newly discovered" originals rather than duplicates, they can be highly deceptive, especially when they appear in the market alongside newly discovered or less-understood cultures.24
