Rare Jeannette - MacBeth Evans / Corning Lampshade Collaboration

An unusual handing lampshade Circa 1938 with Jeanette Glass Herringbone Pattern and Corning Glass Cremax rim . Flying Geese , clouds & stars all encompassed by the herringbone pattern and satinized Pink .
Clear rim positively Corning Cremax Clear . The Jeannette Factory and the MacBeth- Evans Factory in Charleroi Pennsylvania are a mere 30 miles apart ! Does anyone know who made it ?
Please Contact me if you have any information or guesses . Thankyou . Roy .
