Game Worn MLB Jersey Guide (1970-2012): Sixth Edition
So What’s In It?
The new and updated Sixth Edition for 2012 is now shipping! This is more than just an update. Besides adding all year specific content up through the 2012 season, the following changes and improvements are found inside:
- Complete detail on flannel jerseys (1970-1972) added to this edition
- A newly complete compilation of every Turn Back the Clock game in MLB from the first one in 1990 through May, 2012. Hundreds of dates, teams and uniforms, hundreds of new facts and photos. We think we got them all—look and see!

Also included:
- Foreword by Paul Lukas, Uni Watch @ESPN.com
- Special expanded chapters on identifying counterfeit authentic jerseys- of both the game worn and non-game worn variety. Be better prepared to avoid great deals that turn out to be not such great deals in the end.
- A 40-Question Exam of game-worn knowledge is included for the reader to test his or her skill on being able to identify counterfeit game worn jerseys; answers included. How many clues can you spot in this penalty-free test of skill?
- Complete charts for team Cool Base jersey on-field use by each team for each year 2006-2012. As MLB makes the gradual shift to Cool Base game jerseys, it is important for collectors to know which years each team used Knit or Cool Base game jerseys, and which teams may have used both styles in a given year. This information is not available anywhere else.
- Updated with dozens of new prototypes, more facts on team issued jerseys, newly discovered photos, more Turn Back the Clock and oddball jerseys.
- Reader Q&A section has been added with answers to my most commonly asked questions.
- Individual team chapters are available for purchase for collectors interested in one team only.
