Cover from Russia with tho maxicards

I have received cover from Russia with two wonderful maxicards from series Weapons of Victory, dedicated to Soviet fighter aircrafts from World War II, issued on 29.04.2011. Both maxicards have special postmark dedicated to 70 Years of Victory in the Great Patriotic War (World War Two).

The Yakovlev Yak-3  was a World War II Soviet fighter aircraft. Robust and easy to maintain, it was very much liked by pilots and ground crew alike. It was one of the smallest and lightest major combat fighters fielded by any combatant during the war. Its high power-to-weight ratio gave it excellent performance. It proved a formidable dogfighter. Marcel Albert, World War II French ace, who flew the Yak in USSR with the Normandie-Niémen Group, considered it a superior aircraft when compared to the P-51D Mustang and the Supermarine Spitfire. After the war ended, it flew with the Yugoslav and Polish Air Forces.

The Lavochkin La-5 was a Soviet fighter aircraft of World War II. It was a development and refinement of the LaGG-3 and was one of the Soviet Air Force's most capable types of warplane. The two aircraft shared a lot of traits including its wooden construction. The biggest change came in the way of a new powerful radial engine that gave the La-5 vastly better performance.The La-5 was flown by the highest scoring allied ace, Ivan Kozhedub, who scored 62 air kills. 

Nice cover with beautiful stamps, and picture of Pskov Kremlin, an ancient citadel in Pskov, Russia. In the central part of the city, the Krom is located at the junction of the Velikaya River and smaller Pskova river. The citadel is of medieval origin, with the surrounding walls constructed starting in the late 15th century.
