If you like old bricks, you'd love the one I've got! It came from a house built around 1700 and it has a big paw print almost an inch deep in it. Either a very large dog or perhaps even a wolf. I guess it walked across the bricks before they were fired. The print is superbly detailed with big deep claw marks. It has pride of place on top of my filing cabinet along with my battery charger, plaster dental cast, old CDs, tin of glue, and a copy of "The Alexander Technique" that somebody lent me a couple of years ago and I haven't read yet.
