Art glass Hand Blown Leaping Dolphin Paperweight Figurine

This hand blown art glass dolphin paperweight or figurine is so unique with its curved body positioning, as if it’s leaping in and out of the ocean waves!  The majority of the dolphin is blue but the thinner glass areas such as the fins, tail, and nose take on a more translucent hue.
Measurements:  Approximately 3” to top of fin and 6” nose to tail.
Condition:  Preowned good vintage condition.  No chips, cracks, or repairs identified.  There is one area detectable in some lights where possibly there is some color swirl in the glass or it has been possibly marred.  However, there is no detectable roughness to the glass so I feel like what I’m seeing is actually inside.  I’ve lowered the price a bit for my inability to determine if it’s a blemish.
