In the collection of a friend living near Montargis, I discovered a old folio containing a variety of anatomical drawings.  The drawings, different of size were kept in an old folio since the time they were created (in my opinion originaly the sheets were bound in the folio).  
On the folio, there is a period label which refers to the anatomical aspect of the drawings and also brings them in relation with the Court of the town of Dax (acommune in Nouvel-Aquitanie, southwestern France, sub-prefecture of the Landes department).  On the label the name of a "Monsieur A Taque" is mentioned (possibly the original owner of the folio).
The folio, composed partially with recuperated 18th century paper has an extra aspect on one of the sheets, showing two older figure studies.
I include some extra photos which are showing the old folio in which the drawings were kept (folio NOT included in this sale).

The present drawing is one of three horse studies in the folio.
