Maine Historical Society
Zebulon Harmon of Portland and David Bragdon of West Durham invented and patented the Zylonite shirt insert that allowed men to wear their shirts repeatedly, changing only the front portion that showed under a jacket.
They advertised the product as a "novelty in gentlemen's neck wear" and something "new, nice and nobby."
