What set these seven painters apart? They didn’t share a common style. They did not receive unique praise from contemporary critics, nor did they suffer equal censure. There is no record that this group socialized exclusively, collected each other’s works exclusively, or exhibited exclusively. In fact, there would seem to be only one exclusive quality the most famous impressionists shared. The core seven impressionist painters were the only seven impressionists in Gustave Caillebotte’s bequest.
