Oil on canvas by the Belgian artist Jacques Ochs (1883-1971). This painting has a unique family history: it depicts the artist's wife, Yvonne Lefebvre, and was given to my grandmother, who worked as a housekeeper for Mr. Ochs. She then passed it on to me before her death. Below you will find details of the pieces in my possession: The main painting: a signed oil on canvas, representing the portrait of his wife. Its dimensions are 39.5 cm wide by 49.5 cm high. The preparatory sketch: I also possess the original sketch used to create the work, measuring 15 cm wide by 18 cm high. You will find attached photos of the canvas, the signature, and the sketch. And even the address of Mr. Ochs's house in Liège, inscribed on the back of the painting. A painting, a sketch, and a historical document – it is extremely rare to find all three together.
