Info on SI for Kids Cards: Sports Illustrated for Kids (SIFK) trading cards have been produced since January of 1989.  Sports Illustrated began producing a “kids” version of its magazine at that time which are still produced and flourishing today. SIFK cards have been inserted into each issue every month since that inaugural issue. They ‘re printed on a light cardboard stock paper w/ perforated edges for separation purposes (IT IS IMPORTANT TO NOTE THAT GRADING COMPANIES WILL NOT GRADE THESE CARDS UNLESS THE PERFORATED EDGES ARE PRESENT- OTHERWISE THE CARD IS CONSIDERED "CUT"). They are strictly limited to a print run in the amount of issues published by the magazine that month. Thus rendering them significantly less produced collectibles than their traditional trading card counterparts manufactured in much larger quantities. There are nine cards per sheet w/ a select few issues containing an add'l four or "bonus" nine card insert sheet included. Since SI for Kids focuses on ALL sports, some of the less “mainstream” sport athletes are featured on these cards before any other trading cards! Some of the standout stars which are depicted on these cards have no other trading cards of them at all- licensed or otherwise. Many hobbyists in the industry see continued value for these cards in the future, especially since the 1996 Tiger Woods SIFK card put the brand on the map! SI for Kids cards are becoming increasingly more difficult to find out in the marketplace than ever before.
