Yellow cloud glass flower frog

This is one of my favorite pieces in my flower frog collection.
It is about 4 1/2" wide and about 3 1/2" tall. What is a little different about this one than most of the others I have is that there is no center hole. Many of my cloud glass frogs are Davidson, this must be a different manufacturer. I don't know enough about it to know for sure. Not much info available about the frogs.
