Victorian bone or ivory travel set

A nice bone or ivory travel set from the Victorian era.  (The pieces are so small on these travel sets that I can't definitively tell whether it is bone or ivory, but most travel sets of this era were made of bone.)  I was pleased to acquire the set and then notice the words stamped on the perimeter:  Jaques In Statu Quo.  Look closely at the left-hand side of the photo for the "IN STATU QUO" imprint.  A fine travel set.
