This was a special comic book produced to benefit victims of a massive flood in the Midwest in the summer of 1993. There were 15,000 books printed, each sold for a minimum contribution of $5 (Malibu absorbed all the production costs) to the American Red Cross. And you could only get the book through the mail (coupons were printed inside the regular comics).
It’s a fairly common book, although a lot of auctions on eBay have a BIN that’s too high. This one’s easy to get inside larger lots of books. It was for a great cause, but this is still a fairly common and inexpensive book today.
A side note: I forgot to put in a bid a few years back when the original cover art by Norm Breyfogle went up for sale on eBay. It sold for $70. Still kicking myself for that one.
