French neo-impressionist painter (1863-1935) who, working with Georges Seurat, helped develop the Pointillist style. Fabulous original pencil sketch of the landscape of Arezzo, Italy, with the famous Arezzo Cathedral dominating the skyline, accomplished by Signac on an off-white 7 x 4.75 album page; the reverse bears handwritten notes in French by the artist, headed "Arezzo." In fine condition.
