First poster:
Bablefish says "YES IS IN GOOD HEALTH THE POWERFUL AVIATION OF THE SOCIALIST COUNTRY!"
Second poster, top:
Babelfish says: "TOBACCOS AND CIGARETTES ARE RECOMMENDED"
Second poster, bottom:
Babelfish says: "TOBACCO FACTORY TORGOVAGO OF THE HOUSE"
And I'm guessing that thing in the bottom middle is just a name, as it transliterates as "N.K. POPOV", so maybe "of the house" means "of N.K. Popov's house"
