The price on this marble is much, much lower than it would have been because of the crack in the backside, but it doesn't affect the murrine at all, and actually sort of adds an interesting feature to the backside. You're welcome to return it if you find you don't like it.
"Nuclear War" - (SOLD)
1.60" This marble developed a crack in the mushroom cloud on the backside, but the murrine is intact on the front.
The mushroom cloud backside - he nailed it, another classic backside to complement the front.
This marble is about when Chris started putting little murrine chips around the main chip. LOTS of them here!
