On the following URL are some icons I'd like to use in a website for a client. This would be commercial work.
The site says "free for public use", what is public use and can I use them in commercial works?

I checked the license at: http://creativecommons.org/licenses/by-sa/3.0/us/ and there it says "free cultural works".
Can anyone clear this up?
