PHILADELPHIA PANORAMA COMPANY
I am writing the first book from the American point of view about 19th century rotunda panoramas. These were the biggest paintings in the world, 50 x 400=20,000 square feet, housed in their own rotundas which were 16-sided polygons. Chicago in 1893 had 6 panorama companies and 6 panorama rotundas.E.Cohn purchased shares in Philadelphia Panorama Company. I have info to share.
