Would you mind posting photos of both sides from directly overhead? The angle distorts the image. Chris
Try using a toothpick to see if those on the back of the head and cheek are bubbles. I'm not sure about the thin line from the shoulder. It could be a crack, but we'd need a better close-up to tell. Chris
I'd be more inclined towards a plating issue. There is a stress point for die cracks at the shoulder area on these that I've found but they usually start from the last fold in the jacket (suit) and follow down the jacket (suit) towards the rim.
