This is my latest acquisition. It is a handbill/ leaflet signed by President John F. Kennedy. He was actually Senator Kennedy when he signed this on November 17, 1959 at the Brandywine Hundred Democratic Committee Banquet at the Scottish Rite Cathedral in Willmington, Delaware.
This is a JFK signature style that is not often seen. There are a couple of pics below.
The third pic is from Charles Hamilton's landmark book on JFK signatures. It is an authentic JFK signature according to Hamilton, and it compares pretty well to my piece, I believe.
