In practice however, this was very commonly disregarded by flag makers as it was far easier and less costly to simply print the flag through and through, with the obverse design mirrored on the reverse. It was also common to see the reverse of the flag bear the hammer and sickle in the obverse formation. An example of the flag demonstrating its "de jure" status as being only one-sided is that of the Soviet flag atop the Moscow Kremlin which bore the single-side official design. For vertical display, the flag was made with the distinct difference of having the hammer and sickle rotated 90 degrees in order to compensate for the change in dimensions. This was common in official practice, however the common flag owner would simply hang the standard design of the flag by the hoist. During the presidency of Vladimir Putin, the Soviet flag is not only used for communism, but as a symbol for Soviet nostalgia, which became a major global superpower that developed nuclear weapons and sent the first satellites, animals, and people into space. It also symbolizes the sacrifices of the Soviet people and soldiers that perished in the Great Patriotic War as well as against fascism. During the establishment of the Russian Soviet Republic, Vladimir Lenin and his comrades had considered the inclusion of a sword symbol in addition to the hammer and sickle as part of the state seal on which the flag was eventually based. The idea was dismissed as too visually aggressive, with Lenin apparently affirmed, "A sword is not one of our symbols." The first official flag was adopted in December 1922 at the First Congress of Soviets of the USSR. It was agreed that the red banner 'was transformed from the symbol of the Party to the symbol of a state, and around that flag gathered the peoples of the soviet republics to unite into one state — the Union of Soviet Socialist Republics'. On 30 December 1922, the Congress adopted a Declaration and Agreement on the establishment of the USSR. Article 22 of the Agreement states: 'the USSR has a flag, coat of arms and a state seal.' The description of the first flag was given in the 1924 Soviet Constitution, accepted in the second session of the Executive Committee (CIK) of the USSR on 6 July 1923. The text of article 71 states: 'The state flag of the Union of Soviet Socialist Republics consists of a red or scarlet field with states coat of arms'. It was ordered with the unusual ratio of 4:1 in proportion and consisted of a red flag with the state coat of arms in the center. However, such a flag was never mass-produced.
