Every two months David runs a charity auction, and the winner gets his mask painted. 50% of the bid goes directly to Barncancerfonden (The Swedish Childhood Cancer Foundation), a non-profit organisation dedicated to collecting money to prevent and combat cancer diseases in children.
The auction is a sealed-bid auction, you can only submit one bid per auction. At the end of the period the highest bid wins the auction. Lowest bid is 1500 USD.
E-mail your bid to email@example.com and write Charity Auction Mask as subject.
