A 'Domain of Neptunus Rex' certificate marking 2nd Lt. C.P. McAleer's ceremonial crossing of the Equator on 24 March 1944. Rooted in centuries-old maritime tradition, these tongue-in-cheek certificates commemorated a sailor's initiation from 'Pollywog' to 'Trusty Shellback,' offering a lighthearted counterpoint to the hardships of wartime service in the Pacific.
