As previously noted, I put the word restoration in quotation marks because, as this link indicates (scroll down), the project completed last year based on work by Hubert Le Gall contains almost none of Valadon's actual possessions, which presumably have been lost for years. Instead, Gall relied on Valadon's paintings and a few photos to reconstruct the setting as best he could.
Below are some photos taken of Valadon in an atelier setting, though not necessarily in the building at 12 rue Cortot in Paris' XVIII arrondissement. These are followed by a few of my snapshots.
Suzanne Valadon at her easel.
Studio view: the painting of flowers is also in photos of mine, below. Her husband, André Utter, also used this studio and some of the paintings might have been his.
Suzanne, her son Maurice Utrillo, and André Utter.
