Info from Licensor: "An unexpected gift. Thank God, all intact. Glass - I immediately changed the next day. To all claims that the truck driver is not to blame, there are two answers:

2) It is not a simple piece of cobblestone or asphalt. It's a piece of broken concrete. And how does that get on the road? Does it fall out from the trunk, or from an overloaded truck?"
