very nice piece great graphic i have sold some super graphic tydol veedol banners with unbelievable artwork by bradshaw crandall they were single sided banners not double sided and brought 1k-1800. But lately aviation related advertising has been doing very well so I think right around 500 is a little low estimate i would say 6-800 if not more. good luck, hope you do well. a little tip dont try to clean it or stick it in the washer machine i learned that the hard way about 15+ years ago.
