Colouring attribution to Andre Leon Larne (a.k.a. Andre Mansion).
Additional inforamation provided by Jason David Wright (14 March1848):
"He [Mansion] did not label his work but the dag was dated 1848 which was in the middle of the period that Mansion worked for Barratt (he was the only one coloring for that studio at that time). As a result and given the breath-taking brushwork, it almost certainly by Mansion."
