The Stadium Events Sports Card Checklist is designed to make card collecting easy. It is a great tool to inventory your Sports Card Collection and the most Comprehensive and User Friendly Sports Card Checklist you have ever seen!!! The spiral binder allows you to flip to a particular set, and creates a flat surface for writing. This feature makes it perfect to take to Card Shows or Sports Card Stores to track the cards you have in a particular set and the cards you need. There are pictures of most sets for quick visual identification, as well as, the league the particular set is from (example: NFL, CFL, College). Since collectors like to focus on their favorite players or key rookies and superstars there is a "Key Cards I Have" and "Key Cards I Need" section for each set. This allows a quick glance to remind you which cards are your priority to get. The Stadium Events is proud to donate 10% of the profits from sales of all Checklists to several nationally recognized Charitable Organizations. Have fun doing what you love and make a difference at the same time!!!
