Happy Pluto Day

Today is Pluto Day, celebrating the discovery of the planet Pluto by astronomer Clyde Tombaugh. But, since it was decided in 2006 that Pluto wasn't a planet, here, we celebrate Mickey Mouse's dog, with these lovable covers to Four Color comics from Dell featuring the crafty canine.
