I just learned about a fabulous free resource – the Digital Comic Museum. You can download complete vintage comic books for free! Most are from the comic book Golden Age (1930s-40s) and all are in the public domain and copyright free. Majority are US comics with a handful of Canadian and Australian/New Zealand titles.
This is a fabulous resource for SO MANY LESSON PLANS in art, art history, design, illustration, graphic arts, U.S. history, propaganda and communications at every level from upper elementary through college.
(Note: if you read Michael Chabon’s Pulitzer Prize-winning novel, The Amazing Adventures of Kavalier & Clay YOU MUST CHECK OUT THIS SITE! It is a like a visual companion to the novel).
