From TURENNE to Baron Desnoyers, engraver, professor, signed autograph letter

  
Henri-Amédée-Mercure de TURENNE (1776-1852), military officer, politician, peer of France. The son of one of his friends "wishes to devote himself to the fine art of engraving (...) your honorable position, your rightly earned reputation have led me to hope that you would kindly grant an interview to Mr.

Bertaut and guide them on the path they should take," particularly regarding the choice of engraver from whom he could learn his art.
