Two stickers were discovered affixed to the windows of the subway train between the Brambeck and St. Pauli stations in Hamburg, Germany. One of the two included a yellow heart with the inscription "I CORONA". The other was in the form of a yellow Star of David and the text: "Coronav virus !!"
The shape and color of one of the stickers embodies the so-called "Jewish star", a badge Jews were forced to wear in Nazi-occupied territories in 1941.
