Jacques Thibaud has signed at the top of the leaf, with a one-bar quote under which he has penned the lyrics Je vous en-bras and dated 1933. Below this are the signatures of Carl Flesch and George Enesco (both undated). Lower on the same page are two other unidentified entries, as well as three more on the verso.

A nice association of three of the most prominent violinists of the early 20th century.
