The oldest surviving piece of original Superman art sold at auction last week for $286,800. And, surprisingly, Superman co-creator Joe Shuster didn't draw it.
In fact, it's the cover to Action Comics #15, cover dated August 1939, and it was drawn by Fred Guardineer, one of DC Comics' go-to cover artists at the time. The cover depicts Superman underwater, saving a disabled submarine. When the issue was released, it sold for a dime.
