Amedeo Clemente Modigliani (1884-1920) often signed his paintings with his surname "modigliani" written in all lower-case cursive. Some cases can be found where the artist capitalized the "M" of Modigliani.
Unlike most artists who sign the bottom left or right of their canvases, Modigliani often signed the upper edge of his portraits.
Modigliani's signatures can be found in different colors, though he frequently signed his oil paintings with black paint.
Signature is rarely sufficient for authenticating a painting, signatures must be checked, but results must be carefully placed in the correct context. A signature is only one element, and not a determining one, in the process of authentication.
