Obviously someone things so. Here's a listing from Jennifer Gasperini, a Minnesota woman who was involved in promoting past Steger Expeditions:
Celebrate the 20th Anniversary of the 1990 International Trans-Antarctica Expedition with this authentic expedition anorak, designed by expedition co-leader Will Steger and manufactured to his specifications by The North Face. This jacket containing Gore-Tex is identical to that worn by the team on their 3,741-mile, historic crossing of the Antarctic continent by dog team, a National Geographic cover story in 1990.
The jacket features reflective patches – on back and front – with the six country flags represented on the expedition: US, China, England, France, Great Britain, Japan and Russia. Stitched-on logos for expedition sponsors Gore-Tex and UAP of France appear on both shoulders. Pull cords at waist, bottom and collar make it adjustable to all weather conditions.
A zipper on the hood provides for a zipped-on fur ruff. Full pocket in front is sealed with flap, zipper and Velcro closure. This bright orange jacket was part of a set provided to expedition support staff, but never worn. Selling for $1,500 with free shipping. Contact: firstname.lastname@example.org
