WOW. This is a huge coincidence! I hadn't been to your site in a long while and I remembered to check it out. I was JUST thinking about these book with the really cool flip animations the other day! I used to love these when I was a kid! I was just thinking about looking on Ebay for them... thanks SO much for posting these, this really takes me back!
Well, you should go back in the archives a bit -- I posted a Road Runner BLB that had the flip-book thing too!
Please keep your comments relevant, I delete all spam! Thanks.
