About Us

 

Mary L. Martin Ltd. Postcards is a family owned and operated business, and also the largest postcard shop in the entire world.

 

Started over forty years ago by Mary L. Martin, she quickly became known around the world as an expert in antique and rare postcards.

Today, her daughter continues the namesake, and has become known for having the same expertise her mother possessed. Having written over twenty five books on the subject of postcards, it is no wonder that when people think "postcards", they think "Mary L. Martin". Mary and her son Joe now run the business.
