I love sending Illustrated envelopes through the mail! I have done this for years with my Grandmother and she always says how much she loves the surprise of getting one of these in the mail. This envelope was done with colored pencils and feature a very special piece of Connecticut history. Mystic Seaport Lighthouse was built in 1966 and is a replica of the 1901 Brant Point Light in Massachusetts. It is active but not an official aid to navigation.
