Green Bay Packers NFL Jersey made by Reebok in Korea, so, likely in the early 2000s and more specifically 2004 as a guess, the number is 04 and the name  H. B. White is on the shirt, which I have been unable to find any info aboutI assume it was made special order. It is a size adult men XL measuring:

-27 inches across chest under pits laid flat     -34 length down middle of back

This jersey is in very good condition, all printing is excellent shape, and if you are related to the folks who may have made the shirt then this is an amazing find, and no offense to H. B. , but a little careful heat and or a seam ripper and the that could be removed leaving the 04 and a fine looking Reebok On-Field Equipment jersey. If anyone has the scoop on the name, I'd love to hear from you. Please ask any questions before biding if possible, be sure the size is correct for your needs, and check out all the pictures for condition. Take a look at my  other listings for dozens of other sports jerseys from NBA,MLB, WNBA, NFL and NCAA, I am going thru years of picking and using this time at home to get them all listed, several hundred in all, please feel free to ask for anything you may be looking for, I just might have it, Thanks, stay safe and be well.
