The ОСОАВИАХИМ (Union of Societies of Assistance to Defence and Aviation-Chemical Construction) was the precursor of the DOSAAF. Like the DOSAAF, the ОСОАВИАХИМ was in charge of the formation of Red Army reserves. It also provided via members’ fees, lotteries, etc funds for new aircraft and airships. This poster is calling its member to do just that.
No luck with this airship fundraise: the Soviets never employed Zeppelin rigid airships types. They planned to built some, but none were produced in the end. One of Umberto Nobile‘s semi-rigid airships was known as the W6 ОСОАВИАХИМ though. By the way, this one looks a lot like the USS Los Angeles.
