First off, I really like the works.

Second,I need to verify this is safe to use.  When you say commissioned for OSARE, I would assume they had no agreement that they own the rights, or any part of it, such as resale.  Did you specifcially retain the rights to release this as CC0/Public Domain?  

I only ask because I have a strict legal team, and they want to make sure there were no restrictions placed.  I trust that you do, but I'm looking for clear verifications to satisfy my legal team.

- Thanks!
