This is a great quality map with an easy wipe surface. The seller provides a top service with very quick delivery, great price, the map arrives in a sturdy tube. At the moment I can't see any reason why this won't last me the three years I plan to complete the Knowledge in. I've also purchased the Premier Map of London from this seller. My mate has them glued to his living room wall, I've decided to glue them to hardboard for ease of use and to keep the wife happy.
