I have a set. They are copyright 1999 by Topps, as well as Roxanne Toser Non-Sport Enterprises, the publishers of Non-Sport Update. They had published a book called The Beat Goes On, which is an unbeatable resource for Original Series Wacky Packages, with illustrations of each series, etc. I assume that TSE published/printed these binders as well. Cover art design for the binder series by Jay Lynch. The spines of each of the four binders are designed so that it reads "Wacky Packages" across all four when they are shelved together, in order. I have to admit, it looks pretty darn cool on the bookshelf. I purchased them when they first came out (and glad I did, as I couldn't afford them now!).
