Picked up this button a few years ago

This is an American lapel button celebrating the 60th anniversary of Armour & Company 1867 - 1927.
Armour and Company started in 1867 and soon became the worlds largest food processing manufacturer with its head office in Chicago
The back of the button is marked " Bastian Bros Co Rochester NY the maker.

I picked this button up at a garage sale in NSW Australia a few years ago for $15.00.
Its a gem and i dont think there are to many of these left in the world
