The knight on a horse, called Vytis, has been a
symbol of Lithuania for a long time. He can also be found on most coins from the country. An exhibition in Kaunas (which opens on Tuesday) shows his history on Lithuanian coinage.
Vytis: From the Lithuanian Denar to the Euro (Information in
English and
Lithuanian)
Bank of Lithuania, Kaunas, Maironio gatvė 25 (13 May - 30 June)
Attached are images (from the Lithuanian version of the media release) which show three different coins featuring the vytis. You can see larger images here:

this topic)
