Reminiscent of the map motif jacket from the World Masters in Minnesota sometime back in the last century.
Was that the tyvek jacket? A classic!
Something like tyvek. Something like paper. I've had one sitting untouched in my closet for nearly 17 years, and last week I wanted a really lightweight jacket, so I pulled it out. Perfect. It tore the first day.
Tom Bruce has a shirt that he found on the rack in a discount store made from fabric that is inexplicably a print of the original edition of the Ward Pound Ridge Reservation orienteering map. Quite a find.
