2002 Topps e-Topps inserts

[deweyinthehall]

I'm working on a 2002 Topps master set. I've had the 5 cards pictured below on the right in my collection since taking them from packs 23 years ago. They are e-Topps ads featuring Clemens, Garciaparra, Gonzalez, Piazza and Pujols.

TCDB doesn't even list them as inserts, which is odd because they list some of the most random, long-forgotten advertising ephemera that were contained inside Topps packs over the years.

Without that, I have no checklist. I assumed I had the whole set because I ripped a LOT in 2002, and only ever got these 5.

But, I looked on eBay to see if I was missing any, and sure enough a Bonds showed up (left, below). It was the only other one I could find, so I assumed I was missing it and ordered it.

It is identical in every way with the others right down the the copyright data on the reverse. BUT - while the other 5 are on regular card stock, the Bonds is thick, almost like relic card thick.

So - here's my question - was the Bonds thick card pulled from some other 2002 Topps set? If so, does there are thick versions of the other 5 out there somewhere, and a thin version of the Bonds?

Appreciate any help with this mystery.
