These Zippos belonged to US soldiers who engraved them with texts that are sometimes optimistic, but more often pessimistic as hell. A unique collection of 282 Zippo lighters from the Vietnam War era were recently put up as a single lot at Cowan’s Auctions in Cincinnati, Ohio. The lot was the culmination of years of painstaking research by American artist Bradford Edwards, who picked up many of the distinctive lighters on site in the former war zone during the Nineties.
