Symphony Clip Art License

[Samuel Mehrbrodt]

Hi,

I'd like to reuse the nice Clip Art from Symphony [1] in LibreOffice. 
Can someone tell me which License they have? Is it under the Apache 
License or copyrighted by IBM?

Thanks
Samuel

P.S. Thanks to IBM for open-sourcing Symphony. It has really nice 
improvements.
