Three violin manufactures have all done business for years on the same block in the small town of Cremona, Italy.
After years of peaceful co-existence, the Amati family decide to put a sign in their shop window saying:
We make the best violins in Italy.
The Guarneri family soon follow suit and put a sign in their window proclaiming:
We make the best violins in the world.
Finally, the Stradivarius family put a sign out at their shop saying:
We make the best violins on the block.
