Experts restore rare Dutch Golden Age map found stuffed up a chimney

A rare Dutch Golden Age map of the world that was discovered, scrunched up in a ball, in a house in Aberdeenshire is due to go on show at the National Library of Scotland this month. Claire Thomson, a conservator at the library, describes its preservation as the most difficult project I have ever tackled.
Nova Totius Terrarum Orbis Tabula (new map of all the world) was designed by the Amsterdam-based cartographer Gerald Valck and was probably published in London by George Wildey in around 1690.
