Condensed from Wikipedia, “Puʻuhonua o Hōnaunau National Historical Park is a US National Historical Park on  the island of Hawaiʻi.  (It) preserves the site where, up until the early 19th century, Hawaiians who broke a kapu (one of the ancient laws) could avoid certain death by fleeing to this place of refuge or puʻuhonua. The offender would be absolved by a priest and freed to leave. Defeated warriors and non-combatants could also find refuge here during times of battle.”  The 1980 card has serrated edges, its 10-cent stamp, and a faint postmark.  It makes no reference to a national park, though.  Grade: 1
