The first photo shows Lena Horne and Commandant Berneaud of the SS Liberte; the painting between them is "Calendar," by Margo Hoff. The smaller painting on the left is also by the artist, and the way the work is displayed suggests the possibility that there was a Hoff exhibition (or a group show including her work) aboard the Transatlantic ocean liner. The ship was built in 1929 in Germany; captured by the British during World War II; sank in 1946; was subsequently raised and refitted, and saw service as a passenger liner from 1950-1961—this would seem to date the photo to the 1950s. The liner made an appearance in the classic film Sabrina (1954), starring Audrey Hepburn and Humphrey Bogart.
