I found the following:

A Rourouni Kenshin poster calendar of supposedly 
1999 or 2000 or 2001. It's 6 posters, 2 months 
per poster, from Kyoto Arc over Kenshin and Kaoru 
holding their child. The cover's removed.

A Kenshin Movie poster of Kenshin standing in the 
center surrounded by the characters like Sano, 
Kaoru, Shigure, Toki, etc.

A Kenshin poster of a blue tinted Aoshi closeup 
with a normal Aoshi full body.

A Kenshin poster, watercolor, with Kenshin 
standing in the center and a large Hiko and 
Saitou standing back to back, grinning.

A Kenshin poster, watercolor, of Sanosuke running 
in the center, with a large Shishio and Seta 
standing back to back, smiling.

A Kenshin poster, Kyoto Arc, cel style, Kenshin 
standing in the center drawing his sword over his 
head, and Shishio, Aoshi, Saitou, Sano, Kaoru, 
Yahiko etc. surrounding him in different scales.

Most posters are in good condition, but they do 
show marks of poster pads, including small rips 
and stuff.

The set (sold only in a set) is $12 incl. s&h. I 
think that's ok for 11 posters.

Then there's this cute little duo of Slayers 
posters:

-Slayers NEXT group shot, cel style, showing 
Lina, Zel, Amelia, Gourry, Xelloss and a chibi 
Martina.

-Slayers TRY, Filia praying & criying, Lina 
holding the bow of light, and a line drawing of 
Valgarv spreading his arms and wings, messiah 
like.

That's another free set with $5 for s&h.

I only take PayPal for these. And remember the 
risk of bonus anime items ;)
