I reached out to a local lady who IS knowledgeable to ask her about the blank. While she didn’t know the blank she did know that this piece was not Corn Flower but instead had a cutting called Dream Flower.
A recommendation from the Corn Flower Glass Collecting Facebook Group led me to make an inquiry of the Museum of Dufferin. The Museum holds the world’s largest public collection of W. J. Hughes Corn Flower Glass.
The curator very kindly sent me some information about the Dream Flower line, verifying that is considered ‘fake Corn Flower’.
The line was produced by George Zimmer Limited of Toronto sometime during the 1950s-1970s.
A hint to the cutting are the spotting lines which stick out past the flowers.
Very interesting. I still don’t know who made the blank though!
