Juliet is a fictional drink, served exclusivly on performances of William Shakespear's "Romeo and Juliet" in the theater "Deutsches Theater" in Berlin.
Helleborus Niger, commonly called Christmas Rose, is the flower that was used to brew the potion Juliet used to appear dead. The flower is poisonous and can kill in a certain dose, but if consumed in minor amounts, is told to be stimulating.
The signet recalls that plant in a simplified icon.
Furthermore, three versions where developed to maintain the appereance of the signet when used in different sizes.
