This handmade cribbage board is mounted with 4 brass screws onto a wooden base. The cribbage board itself is made from fossilized bone and measures approximately 5 2/3" long and 2 1/3" across at the widest end. The wooden base is 7" long, 3 ¼" wide and about ½" thick. The bottom is covered with green felt. The bone shows 3 layers which you can see clearly in the picture with the end view. I don't know the age of the board, but we have had it for many years. The bone itself is obviously extremely old. It did not come with any pegs, but if you wish I can supply 4 brass pegs that fit perfectly and match the four corner screws.
