Can Anyone Read Yiddish? Can you read this signature on photo?

Yiddish / Hebrew signature? Here is a 1928 drawing of composer, Michel Gelbart, by Morris J. Kallem. It is signed in pen but I can't read it. Gelbart wrote many Yiddish songs and the art is a page in one of his sheet music compositions that I found today. I think it might be Kallem's signature in Yiddish. Can anyone translate it? Thx.
