Seriously, I thought this was a criminal.
WANTED is jumping from the poster.
At a glance, key word is MISSING and that should be what the eye catches when pass by.
Also, movie posters look much more important than a missing person. Compare the size.
So if this is a thing of importance, instead of delaying a train to announce and read all of this to the passengers (who are btw always unhappy when the train stops), why don’t redesign the letter-sized notice into a advertizing-size, eye-catchy poster?
Instead of paragraph describing what a person was wearing when was seen last time, it can easily be shown with a picture. (the drawing is simple and fast illustration of an idea; the color of the clothes should be presented, and the person should be the of the real height and look)
