Conclusion

- There was no clear conclusion , Dr. Wandless had to make a quick descion since she might lose her job.

Art Historians Assumptions

- This painting was simillar to another one in Barnes Foundation in Merion, Pennsylvania but smaller.
- Cezanne did not sign all his paintings.

Scientists Assumptions

Dr. Simpkins
- He examined fluorescence from the surface of the painting using both short-wave and long-wave UV excitation from a mercury lamp. - Some areas in Cezanne's painting were brighter than the rest, he added that it matched another painting by Cezanne in Brooklyn. - He Concluded that the painting isn't fake.
Dr. Montoya
- Used x-ray fluorescence (XRF). - She discovered that all the pigments that were used matches the time when Cezanne lived. -She concluded that Cezanne might have drawn this painting.
Dr.Andersen
- Used infrared spectroscopy (IR) to detect anomalies beneath the paint. - she assumed it might not be Cezanne's work at all. - IR refractography detected that there is another painting with Charcoal underneath Cezanne's painting. - There were singals of an animal glue used in this painting whereas Cezanne was not famous of doing any underdrawings.
Dr. Pruschy
- Pruschy used Ultraviolet (UV) spectrum to know whether Cezanne drew this painting or not. - He assumed that Cezanne's painting was supposed to be older.
