Many thanks to friend Mr. Vitaly Rymkevich of St. Petersburg, Russia for sending me this FDC.
This stamp was issued to commemorate circumnavigation of the sail ship Kruzenshtern in 2006.
Kruzenshtern is a Russian four masted barque and tall ship that was built in 1926 in Germany, under the name Padua (named after the eponymous Italian city). She was given to the USSR in 1946 as war reparation and renamed after the early 19th century Baltic German explorer in Russian service, Adam Johann Krusenstern (1770-1846).
In 1995/96 she made a trip around the world in the trail of her namesake. She again circumnavigated the globe in 2005-06 to commemorate the 200th anniversary of Krustenstern's circumnavigation.
