Europa Bridges on cover from Germany

I received cover from Germany with stamp Europa 2018: Bridges, issued on 3.5.2018. On this stamp you can see "Rheinkniebrücke" in Düsseldorf in the front and the Oberkasseler Brücke in the background. These are two of the of the 7 bridges built (between 1951 and 2002) in Düsseldorf to cross the Rhine river. Second stamp is definitive flower stamp Common bluebell, issued on 8.6.2017.


Thank you Melanie!
