When I visited a friend recently I asked about this painting and was told that it was a May Show entry called "Starfish" painted by Janet Moore.   A sticker on the back of the masonite board confirmed that this painting was from the 38th May Show held in 1956.   

I went on-line to see if there was any record of the art entered in the May Shows and found that there is a list of the artists but very few images available of the art.   Here is a link to the Cleveland Museum of Art archives May Show database.

It is certainly unfortunate that a photographic record  of all the art submitted to the May Show was not maintained.

Here is a link to artoftheprint, a site which has a bio of Janet Moore.
