This curious stick pin for 'James Wolfe' is most likely a souvenir/commemorative piece in early 1900s. General James Wolfe was a British army officer, known for his victory over the French at the battle of the plains of Abraham in Canada in 1759.  The portrait measures approximately 14mm in diameter, and 54mm (2.10") in N-S. (without the pin stopper) The pin stopper at the bottom tip is a contemporary one, and is added by us. Overall in good wearable condition.
