Absolutely Stunning Antique Reverse painted glass lampshade; large, must see

This is incredible; it was found at a NJ estate sale and is a reverse painted lamp shade; it is so beautifully done, a cottage, flowers, trees, pink, green and so detailed - no chips or cracks, this is a work of art just sitting on a table by itself - or for it's original use as a lampshade. Measures a large 24" x 10".
