From reading Utrillo's bio on Wikipedia, he died in 1955 around the time my parents got married and set up the apartment. I suspect they were prints that someone either gave them as a present, or perhaps my mother liked them and purchased them for the new apartment. We'll never know. But here are the prints. I've including information below where these came from if you are interested in purchasing them. No copyright violations are intended. The bottom one I believe is entitled: Le Maison de Mimi (Mimi's house). Not sure about the top one. Anyone know?
