Vintage Handmade Bubble Trap Glass Elephant Paperweight

Great looking modern elephant. Bubbles look awesome. It measures 4" tall and 2" wide. There are no cracks. There is a mark at the bottom of the piece under the elephant's left ear and diagonal from the tail. You cannot really see it, but you can feel it. I tried to get a photo of it, but it is tough as the bubbles show up all the time. Please see photos.
