Time traveling hipster

Time travel, thought to be pure science fiction… well until this photo surfaced. It is being called the time travelling hipster. The photo was taken in 1940 at a bridge opening in Canada. If you look at the picture everything looks normal but then you see the man up front wearing the glasses. People believe he is wearing a printed t- shirt which was not around at the time. Other people believe the t- shirt is actually a sweater with designs sown into it
