Since my content has to be approved by a moderator, I'll give it a try and see if this passes. If it doesn't, I'll PM you. Total of 21 books, most in good condition. The one exception being Champions 4th edition which has a broken spine. All of the pages are there, but some are coming loose.

I also have a few Champions Comics, because at one time Champions was so popular they tried to spin off their own comic series:
Hero Comics: Champions issues 2, 3, & 4 Marksman issues 1, 2 & 3
Eclipse Comics: Champions Mini-series 1, 2, 3, 4, 5 & 6
All comics still in plastic sleeves and in excellent condition.
I also feel obligated to mention that some of the books are available on this site in PDF format. I realize what I've listed are now of more of interest as collectibles as the rules system has evolved. I have fond memories of playing Champions. My gaming group was totally into Dungeons & Dragons in highschool. I played Champions all through college, usually as the game master. Still, they aren't doing me any good sitting in a box.
