These books are great for horse racing enthusiasts who want to learn about the stakes winners from 1965 and 1966. To use them, simply open the pages and start reading through the details of the races and the winning horses. When handling the books, be gentle as the bindings are breaking down and the pages are a bit fragile due to their age. To maintain them, store them in a dry and cool place away from direct sunlight. This will help prevent further yellowing of the pages and damage to the covers. Avoid getting the books wet or dirty, as they already have some soiling and minor tarnishing.
