Old school tombstone kickboards?

When I was a kid, we had hard, very buoyant tombstone kickboards. My favorites wore down to be very smooth and thye had white writing on them. They were larger than the firm ones they seem to offer at Kiefer etc. now. Does anyone know if they still make these, and where I might get one? If you don't know where to get one, you can just feel the nostalgia with me...
