I received a call from the person who wrote to me and we had a great conversation. I mentioned that I had a problem with the artists not getting any payment for their donation/time, and a few other concerns. We had a great back and forth and I really enjoyed it.
The next day I was informed that after our conversation, the person who called me spoke the head of the organization and they decided to split the winning bid with the contributing artist 50/50, and let the artists to set the starting bid, so they will feel comfortable with the entire process. There are also some other perks. How refreshing!
Because of all of this, I have agreed to donate, and will be shipping my piece to them hopefully today. I will post info about the art auction and the movie as soon as I have more info to share.
