Source: Photograph (2010) by WTL© of a scene in the port of Havana.
Comments: The photographer is standing alongside the seawall on the Avenida Carlos M. de Céspedes (also the Avenida del Puerto) looking at the east side of the Port of Havana. Although it may look like flame in the upper center is coming from the ship's smokestack it is actually coming from a refinery behind the ship.
Trivial humanities issue: The professor-photographer thought the image's visual ambiguity was clever. What do you think?
