I honestly don't know much about Flottorp, but I do know they were based in Grand Rapids, Michigan during WWII and I always thought the logo was really cool, so I finally made it into a vintage style sign. This sign measures approx. 27" tall x 86" wide. It is currently available for $595 plus shipping. Please email matt@mattzudweg.com or call 231-206-7660 if you are interested.
