Surely you’d get a professional hair work artist to execute the more complicated looking designs but maybe not. I found a similar work that has a scan of the title page, which states that it was printed in 1865, but by a different lithographer/printer. So I am not sure it is the same one, but the date looks accurate. Not finding much more about P. Florentin but Lemercier et cie were well known lithographers. Later they did photogravure, too.
