[Clipart] Copyright or Public Domain figurine?

[Jurgentje]

Hello,

on the Open Clipart Library, we've put some figurines of Domo Kun. (look at

http://www.openclipart.org/cgi-bin/navigate/recreation/toys?page=2)

On your website you state that the site is copyrighted.
Now... would you allow that specific (set of 2) image(s) to remain in the public domain, or do we have to remove the image from the clipart Library?

Thanks for your time and inspiring figurine.
Jurgen.
