The Authenticity of Paul Cezanne Painting

Curator's Reccomendation

Don't buy the painting

The presence of a single evidence that disproves authenticity shields all positive evidence proving authenticity

Evidence Disproveing Authenticity

IR Spectra: composed of cadmium yellow which was used after Cezanne died.

Possibility of underdrawing

Painting is unsigned

Doesn't prove it's Cezanne's

Absence of evidence about whose painting it is, doesn't prove it's Cezanne's

Absorbance of the painting = 0.6 while absorbance of the paintings in the 1880s = 0.15

The difference may be due to contaminants

Evidence Proving Authenticity

IR spectra: The binder used was animal glue

proves that it was made before 1930
