On October 21, 2000 Lithuania issued this one lita stamp (Sc #677) as a part of its municipal coats arms series. Stamp depicts the arms of Raseiniai (pop. 11,200) in west central Lithuania. The exact meaning of the springing lynx is not known.
From heraldry-wiki.com, "The arms were granted at the same time as the city rights, on March 20, 1792 by Stanislaus Augustus, ruler of Lithuania and Poland...The lynx was officially restored on October 25, 1989."
