In 1990, when closed archives became available, an investigative journalist Valentin Skoryatin published an article in № 5 titled "Who, me, shot myself? You don't say!" where he talked about the mysterious death of Mayakovsky and the inheritance Lilya received after he passed away. He also made public the NKVD serial numbers of both Osip and Lilya Brik (№ 24541 and № 15073 respectively). Osip received his ID of the 7th secret department in 1920, while his wife was granted it in 1922. The article was later published as part of the book "The Mystery of Vladimir Mayakovsky's Death. New Version of the Tragic Events Based on the Late Archive Findings".
