The Cunard Line's "Queen Mary" sailed the seas from 1936 through 1967, setting a few speed records for crossing the Atlantic, as well as ferrying troops during WWII (painted battleship gray). By the 1960's, her future was uncertain; but the city of Long Beach, California put in a successful bid to keep the ship and renovate it as a tourist destination.
This photo was taken 8 years later. Permanent gangways were built (visible to the left) so that you wouldn't have to be flung aboard via a giant slingshot. We can also see an ocean, but I forget which one. Who can keep track! See that oil tanker? It's actually a whale, able to appear as an oil tanker in order to protect itself in the wild. Nature is magical.
Too bad you nobody is standing next to this propeller, it's hard to tell how big it is; the average person's head would not have reached the bottom of the lower blades. Anyway, the QM had four of those babies. There used to be a large tank on board the ship, like a giant swimming pool, and you could look down in it to see another propeller.
