Large & Beautiful Portrait Circa 1950-1960...the Girl In Pink...signature?

Large & beautiful painting from the 1950s-1960s which represents a remarkable portrait of a young girl dressed in pink...the work is signed lower right but the signature is difficult to understand / see detail photo 9: it is a painting which reflects a rather breathtaking accuracy and sensitivity of quality...The identification of the artist can sometimes reserve an excellent surprise because on the technical level it is undeniably great art / advice to research enthusiasts .. note: it is a work to be restored because we can see some gaps and cracks which look like small blisters: the restoration work is quite basic to be corrected by someone professional because the paint adheres perfectly to its support ... note that the condition of this painting is significant of a canvas which was exposed not far from a heat source (radiator or fireplace) ... there are today techniques consisting of "water glue" which make it possible to remedy this ... Canvas size: 55 cm x 46 cm Frame (wear): 68 cm x 59 cm - ask me for more photos if needed -
