This photo was taken in 1941 and the guy circled in red seems to be a time traveller. He is dressed with a modern jacket and a shirt with a logo, and he seems to be handling a modern camera. A very sloppy time traveller.
This photo was taken in 1964 by a french photographer in the coast of Queensland, Australia. He claimed that it was a sea monster while some say it is actually a tarp. There’s no actual explanation.
