Commentary Anselmo spying on Camila and Lotario through the keyhole.
Vierge's style is absolutely masterly; his figures are detailed and real; remarkable detailed setting too.
Notice also the perfect use of shading.
Usual in Vierge's illustrations, some element in black creates a worth noting contrast.
His short and fine drawing lines imitate etching. 
Notes 1 - Vierge's original drawings (Chinese ink and wash) were reproduced by photogravure (notice the plate mark); the specific technique used, heliogravure, allows an excellent reproduction both of the original wash halftones and of the lines.
