The Royal Geographical Society issued this map in limited edition through John Pinches, London, in 1976. This is the ultra rare version made in London, the birthplace of the Royal Geographical Society. The few maps of this type occasionally seen on the market today are typically those that were produced in the United States by the Franklin Mint's US division, not this rarer version produced in the United Kingdom.
This map is hallmarked 925/1000 for Sterling Silver and has four small symbols: J.P. for the maker John Pinches, a Lion Passant, a London Assayers Leopard Head, and a 76 for 1976. The hallmark symbols are seen under the 180 degrees Longitude East marker on the map. The Sterling Silver content numbering is to the left of that under the 150 degrees Longitude East.
This map is in excellent vintage condition with it's original frame, matting, and acrylic cover. It shows little sign of it's over 43 years of age with a few very minor indentations to the frame. It makes a remarkable showpiece - the best I've seen. It includes a certificate of authenticity and original letter detailing the story of it's creation.
Pinches was established in London in 1840. It struck a medal to commemorate the opening for the season of the Crystal Palace in London in 1854, and was a prominent maker of medals for years thereafter.
