This listing is for a #24 copy of Unknown Worlds, published by American Comics Group from 1963.  It shows wear along the right hand side of the front cover and at the top, and there is a place on the bottom staple on the spine where the comic cover is torn away from the staple.  The back cover is in good condition but for an odd crease on the bottom with no color loss.  This comic was read, put in plastic and boarded for decades.  If you would like to purchase more than one of the Unknown World comics, they can be shipped together.  Just ask.
