Dick Tracy, Calling Dick Tracy.

Do you remember Dick Tracy the cartoon?

"The hard-hitting, fast-shooting, and supremely intelligent police detective of the 1930s."

He had a hard face with some serious straight lines. If he was real he could have used his own chin or nose a ruler! I suppose that's what you needed to look like to be a good detective then.
One of the great things about the cartoon was his watch. It was a 2-way radio giving him contact with the police, none of this 999 crap.
Now if i am correct this would be the first hint towards mobile phone technology, way before Kirk or Spock were flipping the tops of their communicators asking a portly scotsman to beam them up.
(By the way i just found this while googling scotty)

Im sure at some point during his fictional life Dick must have been thinking to himself "why can't i get this damn thing to call that girl i met at the bar last night". Well Dick your prayers have been answered.
