I think the plaque belongs on that Kalanianole Hwy property cited in his “birth announcement” posted in the Honolulu newspaper....
If you read articles in WA state they claim that the now torn down building where baby Jr and Ann lived in 1961 was his first home, so it might be dueling states! As for the apartment building, the actual lease for the apartment is good through to the end of June and the owner of the building has been pushing for it to be named to the National Historic Registry since November after Madelyn’s death. I had posted both a video and article about it at that time.
