Flag of the Latvian SSR
From Wikipedia, the free encyclopedia
This flag was adopted by the (former) Latvian SSR on January 17, 1953.
Prior to this, from August 25, 1940, the flag was red with the gold hammer and sickle in the top-left corner, with the Latin characters LPSR (Latvijas Padomju Sociālistiskā Republika) above them in gold in a serif font. The flag was officially replaced in 1990, when the national Flag of Latvia was reintroduced, and its use at public events is now banned.
