Doctor Diamond

Here's one of those generic 1940's super heroes, Doctor Diamond. In real life, he's a guy with a mustache. In his heroic guise, he's a barely dressed guy with a mustache. As evidenced by these consecutive panels, his super power seems to be to make his rather baggy-looking trunks change color. They start out as blue, go unseen in the next panel, then appear white! At the top of the next page, they're now red!
