The British Library in London is holding a contest to win an after-hours Maps and the 20th Century: Drawing the Line exhibition tour. The competition is free to enter and open until the 11th of November 2016 (midnight).
The library sent me some additional information:
Five lucky winners and their guests will enjoy a tour with the exhibition curator and a special show and tell of rare maps from our collection, including cartographic gems like the personal maps of the kings and queens of England, the earliest maps of London and New York, and secret spy maps from the 17th century. Winners can quiz our curator on the stories behind our maps and hear how different items are selected for our exhibitions.
If I were anywhere close to this exhibit I would definitely want to enter this. Good luck to those who do!
