Abraham Lincoln, of course, ran for President of the United States in 1860. His running mate for Vice President was Hannibal Hamlin, a politician from the State of Maine. This was a campaign button for that election. Lincoln won.
A 'ferrotype' is a photograph printed on metal. The pictures fade somewhat, but are still easily recognizable.
The brass-framed ferrotype in our picture comes from Stack's Bowers where it sold for $425 US dollars in a 2005 auction. These are valuable pieces when they are in good condition.
Dennism describes his item as 'mirror-like surfaces' which means it is in good condition. Not only that, the $425 price was back in 2005 and the value has certainly gone up since then.
