     Have you ever heard of Webster Toys? Webster has made good, safe and interesting toys for more than

a hundred years. We sell them and children play with them in different countries from Australia to Canada,

from Japan to Italy. Now we are looking for someone to sell our toys in the Far East. He must be between

the age of thirty and forty. He must have some years of experience of selling toys in the world markets. He

can speak English and at least one other language of the Far East.

     The person we are looking for will live in India and work there in our office, but he will travel for about

six months in a year in other countries and above all, he must know how to sell in our old markets and where

to find new ones! He must know how to make more than before, for himself, and for Webster. 

      Webster wants someone who can stand on his own feet. If you think you are the right person we are

looking for, please write to Mr. Roger Bradshaw at our headquarters.
