A Request for Information

I hope that one (or some) of you might be able to help me.  I am researching the Van Day Truex drawing that is shown above.  The drawing depicts what appear to be two stone bull heads perched atop a vine-covered wall.  Between the bulls is a uniformed man, who might be a gardener or perhaps an attendant of some sort.  This uniformed figure might indicate that the scene was painted in a public place.  Behind the bulls is a dense, darkly painted Cypress tree. 

Truex spent time in France, Italy, and Mexico, so it is possible that this scene is located in one of these countries.  Can any of you identify the location of this scene?  If so, please email me at Jennifer@thepeakofchic.com
