Asama Maru
Postmarked April 3, 1930 from Honolulu, Hawaii
Asama Maru was a Japanese ocean liner owned by Nippon Yusen Kaisha (NYK). The ship was built in 1927–1929 by Mitsubishi Shipbuilding & Engineering Co. at Nagasaki, Japan. The vessel was named after an important Shinto shrine.
Asama Maru set a record of her maiden voyage to California, and surpassed this record on her fourth voyage from Yokohama to San Francisco.
Principal ports-of-call included Hong Kong, Shanghai, Kobe, Yokohama, Honolulu, Los Angeles & San Francisco. The trip from Yokohama to San Francisco typically took 15 days, with fares starting from $190 in second class and from $315 in first class.


S.S. Haleakala (Unused Postcard)
Haleakala was a steam cargo ship built in 1919 by Long Beach Shipbuilding Company of Long Beach for the United States Shipping Board (USSB) as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. The vessel was first employed in the Pacific trade before being briefly laid up. She was reactivated in 1922 and entered the South American trade connecting the ports of Argentina and Brazil with a variety of ports in the Northeastern United States. In September 1926 while on one of her regular trips, she disappeared without a trace, possibly foundering in the hurricane with the loss of all hands.
