Since the book shows future styles even in the fifites, you realize you can go home to the future pretty easy. Maybe going back in time isn't so bad. But you don't want to be some pre-pubescent paperboy stuck in nerdville, either. You look at the historical photos again, looking at the older teens and young men.
The young man driving the antique car is sort of Geeky looking - skinny and wearing glasses. His hair is all slicked back, and he might be in his mid-20s. The teen on the horse looks really big and muscular. Maybe 18 or 19, he has shaggy blonde hair and actually looks pretty handsome. He's wearing dirty, old-fashioned overalls. He's probably out of school, and old enough to do whatever he wants. You decide to try his life out. Pointing to the picture, you show the Barber. "This one!"
"OK. If you're sure. You'll have to wait a while if you change your mind later - I only make house calls once a month." He pulls out a weird-looking brush and a metal comb with long, thin tines.
House calls? Maybe this is far enough back that there is no barber shop. Well, as long as he comes by. The barber starts pulling the brush through your crewcut, and it lengthens with each stroke. In a couple of minutes, you have a dark mohawk, because he has been working just along the middle of your head.
You start to ask him if he is thinking of the right picture. Then you stop and stare in the mirror - what is happening to your face? Your eyes are larger, and the whole lower part of your face looks swollen. Then you realize that he isn't giving you a mohawk! He's giving you a horse's mane! You must have pointed at the horse accidentally!
