estimated year
Each column is a year; its height is the number of records. Hatched columns have a year estimated by the library (in square brackets in the record); solid ones have a year given by the record. The band in the background is the period when the city was officially called Orașul Stalin, 22 August 1950 to 24 December 1960.See the whole page: the names on postcards, by year
