Okay, listed a few more, and I'm done for now
(will wait until all of these auctions end before
I list the rest of my collection)...

Very nice cel of Wakaba from episode 12, and 
a GORGEOUS (and gigantic) entire cel sequence
(18 frames - all-in-all there are 49 pieces!!)
of Anthy from Miki's fantasy in episode 26.

You can search for seller "Lady_Zatara" on eBay.

Thanks!  ^.^
