A professionally done reprint of the original Williams "Little Book" on learning how to service their EM (Electro-Mechanical) amusement games - inscluding pinball, bowling, shuffle alley, and baseball machines.
Reprinted back in the 1980s by a friend (since deceased) we have about 40 copies left. The cover is a thick textured paper like the factory original. The pages paper is similar to a good trade edition paperback - this is a very good quality product. The pages were printed from plates, not photocopies, so the images are crisp and clear, not washed out like so many copies of this book.
Dimensions of the book are 8.5 inches high x 4 inches wide (21.5 x 14 cm), weight is just under 100 gm.
