"Trope is a figure of speech through which speakers or writers intend to express meanings of words differently than their literal meanings. In other words, it is a metaphorical or figurative use of words in which writers shift from the literal meanings of words to their non-literal meanings. The trope, in fact, could be a phrase, a word, or an image used to create artistic effect. We may find its use almost anywhere, such as in literature, political rhetoric, and everyday speech." Source

The banner in the center shouts: ES LEBE DIE ROTE EINHEITSFRONT, or in English, IT LIVES THE RED UNIT FRONT.
