Hi all! Was going through my collection and noticed that one of my foil etched bone shards has this weird line down the right hand side. Not quite sure what it is or how it got there as it's not on the edge of the card so it can't be miscut? I'm not very knowledgeable about this kind of thing so any insight into what it is would be fantastic, or if in fact it isn't a misprint at all please let me know 👍
