This is an incredibly unique and rare book printed by Singer and distributed to new salesmen. It was intended to familiarize the new salesmen with the functions and components of Singer's popular machines as well as give them instruction on how to deal with the FAQs from their customers. There is even a section on the Model 20 Singer and the best way for salesmen to demonstrate it to teachers.
This would not have been a book available to the public and copying/redistribution was expressly prohibited. The books were numbered in the front, and this one's number is 5588. This hard-cover book contains 172 pages and does not contain any copyright info or printing dates as it was designed only for intra-company use.
The book is in nice condition with some wear to the binding. The pages inside are in excellent unstained condition.
