The pictures describe it all. A nicely etched in carvd piece of coal to look like a book. One side has a five sided star within a star flowers and decoration. It also has the name, Guy H. I am guessing this is the artist. The other side reads, this was taken from the Kansas State prison, coal mine, depth of shaft, 720 feet. It is in very good condition. No chips or cracks. The edge surface shows some wear. It measures 3 3/8” x 2 1/2”. Please ask questions. I believe this to be from the 19th century. Buyer will include $12 priority box shipping. Thanks for looking.
