Old Glass Paperweight

I have loved the recent paperweight posts. This is one from my very small collection. It was purchased years ago at an estate sale in Pittsburgh. Given when and where I found it, I'm thinking this might be a Fenton paperweight. Never have been able to verify this. I love the flowers with bubbles. There is no signature. It's fairly large, 3 and 1/4 inches tall.
Any thoughts, Collectors?
Thanks for stopping by.
