I had always wondered what these things were. I had never actually seen one in person but I noticed a couple that were jammed in with some other things on an auction. So I bought a few books I didn’t really want just to see what was up.
They’re actually less interesting than I thought, although they are numbered. I’m not sure how many there were in total, but these are just pamphlets with a little bit of info about upcoming Ultraverse books. They’re not comic-sized, more like 8.5 x 11 (like a regular sheet of paper) and very thin.
I might buy some others if I see them very cheap but these were obviously just info sheets for dealers and were probably sent to comic shops all over the country.
Here's the trick. If you're collecting these comics you are one of the few, so don't go crazy. Just be patient, look for large lots on the cheap and keep your eyes on auction sites. But if you see a gold hologram cover, grab it!
