Vintage vase Applied Blue Swirl on Clear Glass Vase 8.75”‎ Art Glass

Condition is excellent condition. There's one bubble near the top of the vase. I have 2 pictures featuring the bubble in the last two photos.  I believe this is a Blenko piece but I've been unable to locate an exact match of the glass shape. There are several other similar pieces with the exact same blue applied swirl within Blenko's history. There is no pintail at the bottom which confuses me on the history.  The Vintage Blenko Applied Blue Swirl on Clear Glass Vase is a stunning piece of art glass originating from North America in the late 20th century. This abstract art vase features a swirl pattern in blue and textured for a decorative finish. Produced by the prestigious Blenko brand in the United States, this vase exudes a Mid-Century Modern style with a glossy finish, making it a unique and eye-catching addition to any art or abstract-themed decor collection.
