And also receive a Free Collectible Postcard of the Pilgrims Signing the Mayflower Compact! This is a very old postcard from Provincetown, Mass. The very place the Mayflower Compact, our first body politic, was signed! This post card was published by the Mayflower Sales Company, Provincetown Ma, who went out of business many years ago. It is a high quality card with a linen textured front. These postcards were found 13 years ago in the attic of an old Commercial St building where they had been stored and forgotten for years!
