Very Nice condition. There is some minor wear at the corners. They do not appear to have ever been framed or tacked to a wall. Large measuring 18" X 24" Beautiful colors. Both have a small paragraph at the bottom of the picture with a description of the picture. There is some minor discoloration on the picture of Mary where they layed against each other in between two pieces of cardboard. I purchased these at an Estate sale. I would love to know the value of these items. I was lucky enough to find some wonderful information about the artist Virgina Broderick and her work as an artist in the Contemporary style.
