Saw this on Twitter:
At a ceremony today presided over by Gazprom Neft in St. Petersburg, near the Lakhta Center, Putin watched from a yacht in the Gulf of Finland as they raised the Russian tricolor... the Russian imperial flag, and
... the Soviet flag.
There is much more to follow in this story.
Gazprom Russian majority state owned multinational energy corporation was created August 8, 1989 in the final year or so of the USSR (Soviet Union).
It transitioned intact to the Russian Federation on the final day of existence of the USSR, December 26, 1991.
I would be correct to display both the flag of the USSR and the Flag of the Russian Federation at an event or conference by Gazprom.
You are correct.
