letter in the world!
The highlight of the Treasure chamber at IBRA 2023 is the legendary "Bordeaux Letter" with the 1p and 2p stamps of the famous Mauritius POST OFFICE stamps. The valuable letter, provided by the lender via the company Richard Borek in Braunschweig, is today estimated at a market value of up to 6 million euros.
Visitors to IBRA 2023 can already look forward to a treasure trove of world rarities, which will focus on the so-called "Bordeaux Letter" with a blue and a red Mauritius. Around the most expensive letter in the world, further top pieces of German and international philately will be grouped.
