Since i enjoy the possibility of time travel i thought i'd put in my 2 cents as well. Although i'm more of a skeptic here than anything in regard to the photos. I reluctantly say that this photo is very well photoshopped or is a, and i hate to say this, fake. Based on personal assessment of the photo:
1: The guy sticks out like a sore thumb. Since there seems to be a primary source of attention among the crowd i can assume that something more
intriguing is going on than the mans presence, However in the crowd i would have to be concerned that no one is looking or suspicious of his obvious
dissection in physical appearance from the rest of the group. But then again maybe it was just the right moment.
2. This may be just me but the shadows on his face and neck look wierd to me. They dont look natural based on the curvature and the rest of the
shadows in the photo.
3. If he were a time traveler he'd have to know this sloppy appearance would attract attention, UNLESS this state of appearance was considered
'acceptable' at the time (which i doubt) then ...where is the time travel.
4. Also if he were a time traveler what would be the point of being caught in this photograph and not anywhere else, because it seems he has blatant
disregard of his presense in public. I would assume there would be more of this guy somewhere else.
As for the ringclock...I dont think i have enough information to effeciently have an opinion either way. But i do find it odd that it was set at 10:10
indicating that it probably had never been worn or could have been 'planted'
But then again those are just conjectures of mine. I want to believe time travel(ers) is possible but i also have to put everything through my basic
trials of logic, but my opinions arent set in stone either.
