Large Canvas 1920-1930...portrait Of An Elegantly Dressed Child - Signature?

Large and remarkable painting from the 1920s-1930s depicting the portrait of a very elegantly dressed child, posing demurely... The painting is signed in the lower right corner, but the signature is difficult to interpret (see detailed photos). Note: technically and chromatically, it is a sufficiently well-crafted work to suggest the presence of an excellent artist (a treat for art enthusiasts). Aside from the question of attribution, the charm of this work lies in its sophisticated character, as one can easily imagine that it depicts a child living in a beautiful estate belonging to the high society of the time... Canvas size: 73 cm x 60 cm. Frame: 95 cm x 81 cm. Please ask for more photos if needed.
