This a Ronald Reagan Pub hat from the Ronald Reagan Pub.  If you have been to the Library, there is a full Irish pub in the Airforce One pavilion.  The pub was visited by Reagan on his trip to Ireland while President and was disassembled and moved to the library after his death.  It has never been worn and still has the shaping cardboard in the front of the hat.  Please see photos for condition.  I will ship promptly upon receipt of payment.
