The matching plush and silk interior is unmarked. Contemporary accounts of Pope Paul VI describe him as being especially interested in space travel. He, along with millions of others throughout the world on July 29th, 1969 watched on television as the astronauts first landed and walked on the moon. A few minutes after landing, he sent them a message of blessing, salutations and honor. He also sent a special blessing with other world leaders on a silicon disc that was left on the Moons surface. When the astronauts and their wives were granted an audience with Pope Paul VI on October 16th of 1969 as part of the Giant Step tour, he presented them with multiple gifts and medals. Interestingly, this one, a Pius XI award, is not listed as an official award to Aldrin from the Pontifical Academy of Sciences and instead appears to be a personal gift from Pope Paul VI himself. The words "dono dedit" (as a gift) allude to this. None of the other Pius XI medals we have researched contain such language. As such, this medal is one of a highly personal nature from the head of the Catholic church to one of the most famous astronauts of all time. We anticipate aggressive competition among collectors when it crosses the block so be prepared with only the strongest of bids. From the Wendy and Harris Lefkon Collection.
