If you're a Golden Age or sci-fi comics fan, you've read the adventures of SpaceHawk...
...but I seriously doubt you've even heard of Space Falcon!
If you don't know who Space Falcon is, it's quite understandable.
His only, never-reprinted, appearance was in PL Publishing's first and only issue of Captain Rocket (1951)!
In fact, PL was one of the least successful comic publishers in history, lasting less than a year and producing only eight titles, none of which ran more than three issues!
