I had a reprint by a Mr.Light of Whiz #2(1) *, which had Ibis' origin -up to when a thief swiped the Ibistick. He never reprinted #3.That and several hundred other comics were all stolen. I now have finally had the chance to read the rest of the story !
* #1 was the almost unique Ashcan issue, which called CapMarv, "Captain Thunder" - I think. Again, all my reprints,etc., were stolen by that masked thug who hit me when i surprised him.
