Rare vintage longsleeve from around the mid to later 90's. I believe this is the third edition of this design (to the best of my knowledge), but I'm not entirely sure. I'm guessing it's the third edition as the changes in the design seem to follow a pattern...
First edition (1993) is printed all in white ink, and the top and bottom borders of the box on the front of the shirt are the same.
Second edition (1995/96) is printed in white and gray ink, has a larger logo, and the top and bottom borders of the box are each their own unique pattern.
Third edition (1997?) is printed in white and gray as well, but the top and bottom borders of the box are the same as the first edition. This also has the larger logo.
This is my understanding of the Darkthrone UaFM design editions and production dates from the 90's. My information comes from personal experience and knowledge from friends who collect vintage tees.
I could be mixed up with my knowledge of the second and third editions, so if anyone knows different, please contact me about it.
