A red flag with the golden hammer and sickle and a gold-bordered red star in its upper canton with the white thin stripe and green thick band on the bottom.
The flag of the Lithuanian SSR was first adopted by the Lithuanian SSR in 1918, which was a plain red flag. After the Lithuanian SSR was established again in 1940, the flag was a red flag with the national name and a hammer and sickle in the upper canton. The flag in use from 1953 to 1988 was a red flag with the golden hammer and sickle and a gold-bordered red star in its upper canton with a white thin stripe and green thick band on the bottom.
When Lithuanian SSR was established again as a republic of the USSR, it adopted a new national flag on 30 July 1940. The flag was red with the Latin characters LIETUVOS TSR (Lithuanian SSR in the Lithuanian language) in gold sans-serif typeface in the upper canton, and a gold hammer and sickle below the text.[1]
On 15 July 1953, a new flag was adopted. It was modified to meet the new requirements for all flags of the Soviet socialist republics.[1] The top red portion took 2⁄3 of the width and incorporated the mandatory hammer and sickle and red star. The bottom part could be customized by each republic.[1] Lithuania added a narrow white (1⁄12 of the width) and a larger green (1⁄4 of the width) strips.[2] The green and white stripes thus represented the country's wide fields and forests, which serve the country's agricultural and forestry industries.
