Seeing is believing

The largest privately owned collection of Ammonite fossils in Europe ranging in size from  few millimetres to about half a metre.  There are hundreds, or maybe thousands, of them covering every inch of wall and almost every inch of floor throughout the house.  They are all catalogued.  The extra is of one that is more than 50,000,000 years old and the second extra is of one knitted by the owner's wife yesterday!
