I have an original Tony Alva skateboard, it hasn't been drilled and is in good condition. It's the design: it's griptaped and his signature is cut out and the space that is cut out is painted red and yellow. His signature is again on the bottom in red. Do you know how much i could get for it. I couldn't find any on ebay. I heard about $400-$600 and i really want to sell it and get a new bike!!! Thanks a lot!
