Unused Mike Roberts card C7157 of “one of the most treasured historical objects along the Mississippi Gulf Coast,” built in 1848.  We are grateful to Wikipedia for adding this: “The lighthouse has been kept by female keepers for more years than any other lighthouse in the United States. It was listed on the National Register of Historic Places in 1973.”  It was also damaged by Hurricane Katrina but reopened in 2010.  Grade: 1
