Japanese Card Back Error

Was going through the collection and noticed something i have never seen before. The card in question is a Blaine’s Charizard Japanese Gym Challenge. It appears the white area on the card back seems to have a red banding throughout the entire card back. Base set Charizard is just a reference for color. I think it looks kinda cool lol but anyone ever see this before? Thanks!
