The International Stamp Fair in Essen is the world's oldest event of its kind. Every year since 1976, collectors from around the world meet at Messe Essen. The exhibitors themselves are no less international: Postal administrations and agencies from around 30 countries present their new products, stamp or cachets. The 80 dealers, auction houses, accessories manufacturers, research communities and publishers also include many exhibitors from abroad. The fair is rounded out by a lecture programme and the opportunity to seek professional advice from experts.
