An eBay Insert

I've found myself searching for oddball Ranger teamsets lately. One of the sets that I've found was printed as a promotional item (I think) by Jarvis Printing in 1984. The cards look pretty standard, if such a things exists, for promotional cards:

The front consists of a basic picture with the player and team name in a big blue box. The rear features a few stats about the player, including marital status and where he lives.

Other than that, there really isn't much to talk about with this card. However, I do want to briefly chat about what the seller included in the package:

A tri-fold brochure titled "Mickey Mantle: His Final inning." I thought that this would be a neat account of the literal final inning of his baseball career...

...But it wasn't. Instead, it's a brief account of the Mick's hard-partying lifestyle and how that lead him to an early death. Furthermore, it tells of his acceptance of Jesus Christ as his Lord and savior.

Now, I'm a believer of these things - I, too, have accepted Jesus as my savior. But, I don't know how to feel about this. I'm certainly not upset by receiving it. I guess I just feel odd receiving it from someone that I have never met. I dunno, I digress.

What's the strangest thing - if anything - an eBay seller has included in a package to you that you did not purchase or request?
