I picked up my single example earlier this year and was surprised at how large the card (blotter) actually was. I guess most blotters do tend to be oversized. Fortunately, the example I won was in great shape without any ink marks. I think it would be a very difficult set to complete and it will cost you a pretty penny to even acquire one with ink on it (as stated earlier). They are a neat type piece though and one you don't see every day.
