Seven Models in Seven Days, Part 4 - Unknown from Paris

For day four of models, I'm going to feature an unknown guy who shows up over and over and over in my 19th C. academic art collection.  In fact, we have his work documented from 1860 (above by Pierre Miciol) to 1874, a truly remarkable span.  He's not the most handsome fellow, but he's quite nicely built, and he must have been easy to get along with to have kept working so long with temperamental art teachers.  Oh, and his place of employment was the Ecole des Beaux-Arts, a premier Paris institution that produced too many renowned artists to list here.  According to some art history essays I read, his extended tenure as a model would have been rare in the mid-19th Century as most were hired on a one off basis, sometimes literally off the street or out of a labor pool.
