Farini's Lulu?

This may very possibly be an heretofore unknown portrait of The Great Farini's protege, Lulu. Formally known as Farini's son "El Niño," Lulu made his/her debut in 1870 as a girl acrobat. Whether this is Lulu or not, nonetheless, an interesting portrait of a young female circus performer by EISENMANN. (See below comparison of Lulu at different stages, and a close-up showing the unusual shape of her ear from known photo on left of an older Lulu, and on right from this Eisenmann photo. The shape of the ear is said to never change from childhood to adulthood.)
