The pocket scorecard is waterproof/reusable, it is approx. 2&5/8 X 3&7/8 in size (glossy on the image side and matte on the scorecard side). A player would use any regular pencil to record his/her score and erase the card when done. With time (approx. 15 rounds) the matte side will gloss over from the friction of the eraser. The cards can be gently sanded with a emery board or fine sandpaper (350-400 grit) to restore the matte finish.
The cards usually sell for $2-$3. In the past I have sold course cards (Panthorn,Heroes and Wick) and donated the proceeds to the course fund. If you are interested send me an image (as a jpeg) or I can put something together.
Thanks

ps
Lufbery flew a Nieuport 28 in WWI
I down loaded one of the many online images and came up with this design.

I also make 4x6 cards with image/logo on one side and scorecard on the other side. Great for leagues and general play. Also waterproof/reusable. however they tend to last longer before the gloss over.
