I do not remember any FM cover that had a photo of Janet Eden and the airplanes she finished.
However, FM, Jan 57, had a one page article that had three photos, one similar to the Air Trails photo above and two more photos that showed more detail on the models. She painted one for her husband, Dave, and did the other for their friend, John Thorne. Both were different in color and scheme. The cockpits had pilot Indian Chiefs with headdresses. Flown at 56 Nats.
FM, Jul 58 had another article written by Janet Eden and her models. Shows still another Thunderbird with another totally different scheme. Remarkable.
