This is one of those things they used to stick in with the box of comics from the distributor every week. Most comic shops got this kind of solicitation catalog. Most went into the trash, I’m sure. I don’t even think this is particularly collectible but it did have some interesting info.
I know there were 5,000 of each of the holographic covers for the first seven Ultraverse titles. Back in the day these books were hard to find, and when you saw one it was extremely expensive. Seems like I remember some with $100 price tags, and this was back when you could get a pretty good stack of Silver Age Marvel comics for that kind of money.
But I never understood the process. This catalog explains a bit of that: For every 100 copies of an Ultraverse launch title, retailers could buy a holographic cover comic for $4.25. You better have had a pretty healthy comic shop if you were planning on ordering 100 of anything, although this was just before the big comic crash of the 1990s.
