Young Smith & Co New York

Young, Smith & Company operated in New York from approximately 1830 to around 1858.  Backmarks from the partnership generally bear both names but in either order.  W H Smith also sold buttons bearing his name solely.

Most information on this page is from Tice's book, Dating Buttons..., the pictures are generally from buttons that I have handled.
