Auctions - Kellogg's Cards

Does anyone know other sites where Kellogg's cards are auctioned?

Here are some results that I found on the Goodwin auction site.  Just type Kellogg's into the Search box to see the results.

The article below talks about the Benanti collection which included lots of cool Kellogg's stuff.  A few of the Beckett auctions included stuff from this collection.  I was lucky enough to get a few items.  Or maybe I should say that I wasn't smart enough to bid better on more items?
