"Venus and Soldier" is Venus and Mars after Crispijn van der Passche

Macaigne, from France, sells on 21 January 2018 a "Flemish School, 16th century" Venus and Soldier, estimated at 6,000 to 8,000 Euro.

It is a slightly modified copy after an engraving by Crispijn Van de Passe (1589-1611), probably an original design by him ("fecit and excudit" the engraving says at the bottom). As such, it isn't worth the estimate but closer to 2,000 Euro.
