The sculpture contains four inscriptions. Three have been cracked, but the fourth remains unknown. In 2006, Sanborn hinted that there are clues in the first inscription that may crack the last one. Four years later, he released another clue—letters 64 through 69 (NYPVTT) in the final inscription translate to the word "BERLIN".
