We use the well-respected and recognized techniques of
Morellian
and
van Dantzig analysis
to look for inconsistencies that may include, but are not limited to:
the artist’s signature
color choices
brushstroke patterns
anatomy and facial features
landscape details
architectural details
costume details
dimensions
We also consider the composition as a whole and how it fits into the artist’s personal and professional timeline.
In most cases, if at least three major inconsistencies are found, we conclude that the artwork in question is not authentic.
When possible, we use the artist’s catalogue raisonné as a source for comparable works of art. If an artist does not have a
catalogue raisonné, we may also rely on museum collections, exhibition catalogues and records of sale from major international
auction houses.
