Original Colored Pencil Sketching in honor of Esther Jones per Wikipedia... Esther Jones, known by her stage name "Baby Esther", was an African-American singer and entertainer of the late 1920s, known for her "baby" singing style. She performed regularly at the Cotton Club in Harlem. Theatrical manager Lou Walton testified during the Fleischer v. Kane trial that Helen Kane saw Baby Esther's cabaret act in 1928 with him and appropriated Jones' style of singing, changing the interpolated words "boo-boo-boo" and "doo-doo-doo" to "boop-boop-a-doop" in a recording of "I Wanna Be Loved By You". Kane never publicly admitted this. Jones' style, as imitated by Kane, went on to become the inspiration for the voice of the cartoon character Betty Boop.
