Happy 4th of July!!!
Childe Hassam was an American Impressionist. Some of his French Impressionist compatriots also painted flags. I have no idea why it became a ‘subject’. I don’t think it had to do with Nationalism… When I was a child…and even a teenager flying flags everywhere was not a ‘thing’. Being a patriot had nothing to do with flying a flag. Have a happy 4th!!!
