This collection of works in oil on paper shows the diversity of aspects of this technique, from the 17th to the beginning of the 20th century. Represented in this set as well for the representation of the human face, as of the religious scene, it is no surprise that it is particularly rich in landscapes, a genre to which it was most suited throughout the nineteenth century. Indeed allowing painters to work in the plein air while making real small paintings or simple pochades serving as models to be reworked in the workshop, oils on paper multiplied, their small size allowing them to be easily transported. Today, oils on paper, particularly of landscape, have a particular charm, that of the instantaneous, the unfinished, the work in pogress.
