Wow! This makes me wonder this person really means "legend", or something similar to a legend, perhaps a key, or symbols.
Imagine a tourist map of Budapest that shows different landmarks and sights to see.
Many thanks for all your comments. They are very helpful and inspiring. When I tried to complete the sentence, I found out that the Statue of Liberty is not only in New York, but also in Budapest on the Gellért Hill. Somebody makes for us a nice puzzle. "There is no landmark of Statue of Liberty on the tourist map of Budapest." "A Budapesti turistatérképen nincs Szabadság-szobor tájékoztató jelzése."
