The license plate is always described as 62-18 = 44.
But what is that number/letter/random mark after the 8? It is obscured because of the apparent "fold" in the illustration to runs diagonally through the page. Adjusting for that would suggest that maybe it is a 1. If so how does that affect the consensus 62-18 = 44 understanding? What would 62 - 181 = -119 mean? (and why is the image shifted in the first place?)
This painting always screamed ‘red herring’ to me. DMS 44 degrees minutes etc just referencing the location of the image. We also see a fish...intent was to distract reader from the real clue in the border.
