Norman Rockwell Reflections

I have followed the art works of Norman Rockwell(1894-1978) most of my adult life and recently used one of his illustrations to celebrate Father's Day in the US and UK.

Jane went on a discovery tour to learn more about Norman Rockwell and unearthed the wonderful illustration shown below painted in 1959 in oils on canvas (44 1/2″ x 34 1/3″) and used as the cover illustration for “The Saturday Evening Post”, February 13, 1960.1

Ok - so the test is to see who can identify the four artists and their portraits used by Norman Rockwell for inspiration. Put your answers into the Comments Box and defintely no cheating please!!
