I have no particular lesson in mind, but I have always rolled around in my
head, that, the only time this country has truly supported artists was
during FDR's administration. This site offers areas of themes to explore
and perhaps the opportunity to see what artists would achieve given the same
kind of support offered back then.
Ask your kids how they would respond with images to the various themes
perhaps? I'm thinking printmaking and poster art as appropriate avenues.
