Bob Knetzger let me know about this fun museum of old art supplies. Above, The Jon Gnagy Pantograf Drawing Device.
Early '50s box lid for the Jon Gnagy Pantograf. Originally a self-taught art director at 17 years-old for Tulsa's International Petroleum Exposition, he became America's first television art instructor, hosting his first show on NBC in 1946. It was the first TV program ever broadcast from the newly-completed antenna atop the Empire State Building. His "Learn to Draw" art kits are still available today.
