Russian Empire 1866 Multi-Stamp Cover from Warsaw to Baden, Austria

Russian Empire · 1866 · 10 kopecks, 1 kopeck, 3 kopecks

A folded letter (FL) from Warsaw (then part of the Russian Empire) to Baden, Austria, dated circa 1866. It bears an 1866 10k brown and blue stamp, along with 1k and 3k stamps from 1865, all tied by a '1' in four squares cancel.

This cover illustrates the postal routes and regulations of the Russian Empire in the mid-19th century, specifically highlighting the transition of cancel usage in Poland (from Polish to Cyrillic) after 1864. The use of multiple Russian stamps on a foreign-bound letter from a Polish city provides insight into the complex political geography of the era.
