If you look closely, you can see a swastika on the eagle, at a 45 degree angle. As we can see from the other side of it, this banknote was made in 1917, before the first world war even ended.
"When the February Revolution of March 1917 dethroned the autocratic monarchy, one of the first decisions of the Provisional Government was to print new money. The swastika could be seen on the banknotes. "
"Fragments of the Stāmeriene shawl. Unearthed in 1898, it was woven some time during the late Iron Age age, 10th-11th centuries. Latviešu Tautas Tērpu Vēsture (History of Latvian Folk Costume), 1936."
"Before the Nazis desecrated this ancient graphic symbol, the swastika had been a common sight throughout the world. Among other places, you could see it emblazoned on Latvian and Finnish fighter planes (certainly no relationship to the Luftwaffe), the emblem of the U.S. Army’s 45th Infantry Division, even on Coca-Cola and Carlsberg beer bottles."
The Swastika was used as decoration in Kievan Rus', it symbolized Perpetual Motion, the Sun and Fire.
