A curious/squicky entry from the 1952 edition of 125 Ways to Make Money with Your Typewriter, by David Seltz.
Make-Believe Social Letters
Writing “make-believe” letters to persons anxious to receive correspondence is a novel part-time occupation which is reaping substantial returns for an aggressive young man in Passaic, New Jersey.
How It Works
An aged couple, childless, wanted to receive “typical” letters from a “typical” child attending college; a spinster, denied romance throughout her life, requested “romantic” letters from a mythical lover; another woman desired letters that coached her on social and personal graces; still another person, unsuccessful in self-discipline, wanted letters reprimanding him in a fatherly tone. This correspondence filled certain voids in their lives. He typed the letters and sent them out at intervals, as requested. His customers were secured by placing an advertisement in his local newspaper announcing this unique service. He was surprised at the large number of requests for this “make-believe” correspondence.
His rates are $3.00 a month, on the basis of a letter each week. With some 37 subscribers, he has been able to earn about $90 a month.
