Pardubice, Czechia

Postmarked in the Czech city of Pardubice with a postmark that commemorates 100 years of organized philately. The stamp on the right I've seen on another recent cover. It show the Vlčí jámy ravine and is the bottom half of a souvenir sheet that features beautiful sites in the Czech Republic found in the Ore Mountain region. On the left is a Lily of the Valley definitive stamp from 2018. And in the middle is a Red Chateau in Lhota stamp from 2014.
