Perhaps Fergus knows which license applies to those.
See the Alfaerie page for what David has said on this. Note that the Chess pieces are based on Eric Bentzen's Chess Alpha font. I do not know Eric Bentzen and have never had any contact with him. I do not know if David has. I did find a profile on Chess.com for Eric Bentzen that says he is 70 years old and from Denmark. We have always used these pieces non-commercially, but it looks like Bentzen wants to be paid for commercial uses. See The rights to the Alpha Pieces by Eric Bentzen. All David has said about using the Alfaerie pieces is "You may download and use the Alfaerie graphics if you wish."
