New Guinea 1914 Marshall Islands 2s on 2m blue, 3½-4mm spacing from Setting 3, position 4, SG60.
A fine mint example with large part original gum. Centred slightly to upper left though still very fine for this issue.
When the Australian Naval and Military Expeditionary Force occupied German New Guinea in 1914, it overprinted existing stocks of the German New Guinea Marshall Islands stamps with the initials "G.R.I." (Georgius Rex Imperator), referring to King George V. They were only used for a short period of time and are, therefore, very rare and most surviving examples have condition flaws.
Accompanied with a British Philatelic Association (BPA) Certificate of Authenticity (2017).
The Stanley Gibbons catalogue value is £1,900.
