I'm not familiar with it, is the error that it has the world junior stamp on it? I know they categorize errors as uncorrected - meaning all of them are like that, printing errors - meaning a color was missed, a stamp missed or made wrong and corrected errors - meaning they rounded up as many as they could and re-made the card. These are generally the valued cards that everyone hears about. If you could find out that all of these cards were made like this, or just a few correct or not, it helps. It looks like a printing error, but I'm not sure what's wrong.
