Hawaii, Postcards & Airmail from the Kingdom of  the Hawaii

Welcome to Hawaii Postal History. This site is a curated archive and running commentary on a collection of more than 180 items — covers, postcards, and airmail pieces — spanning the 1800s through the early twentieth century. Each envelope, each stamp, each penciled address is a small window into a world that was changing faster than anyone living through it could fully grasp.

The collection divides naturally into two broad groups. The first is approximately 90 covers and postcards from the Hawaiian Kingdom and early Territorial period — used and unused, plain and decorated, mailed from Honolulu to London, from Hilo to San Francisco, from a plantation office to a bank on the mainland. The second is roughly 90 airmail items, documenting the extraordinary moment when the Pacific Ocean, once a barrier measured in weeks, shrank to days and then to hours. Together they form a kind of compressed social biography of the Islands.

As the kingdom weakened, money moved in fast.

1891, Honolulu J  B Castle Sent this Postcard for Committee Meeting

The Future Arrives Disguised as a Committee Meeting

This post card invited members to an Oahu College Jubilee Committee meeting signed by J B Castle- part of powerful elite network that helped shape modern Hawaii.

The queen’s portrait still on  the  postcard  but the handwriting already belong to another world. Someone discussed sugar price and a dinner invitation.

SENDER

J B Castle : Serving as secretary he was a prominent tycoon in Hawaii and is deeply involved in school management.

YMCA Hall: Social elite of Honolulu gathered and operate here during that period.

Key Value: Official Committee Document

“The organizers of the Jubilee would later become the key agents in overthrowing the kingdom.”

The Kingdom Still speaking  in its own voice

1887, Honolulu Postmark Postcard sent by C H Wallace

An 1887 postal card still bearing the royal image of  Queen Emma, canceled at Hamakuapoco, Maui.

At  first glance, it feels calm and ceremonial. But beneath the elegant design lies a Hawaii already being reshaped by commerce, shipping networks and the rising influence of missionary-descended business elites.

Sender:   C H Wallace, a  Maui local is asking a friend  in Honolulu  about travel  by vessel.

Recipient:  Messer H Hackfeld &Co which  was one of  the Big five  that dominated the economy in the late 19th and early 20th centuries.

Scarce Postmark Location: Hamakoapoco, Maui

In 1887, the Kingdom of Hawaii was a bustling hub for the sugar industry, and the small village of Hamakuapoko (often spelled Hamakoupoko in vintage documents) on the north shore of Maui played a crucial role in this era.

The Hamakuapoko Post Office (1887)

​During the late 19th century, Hamakuapoko was a thriving “sugar town” centered around the Haiku Sugar Company and the Maui Agricultural Company.

  • Location: The post office was typically located within the Plantation General Store or the plantation’s main office. In small communities like this, the postmaster was often a plantation official or the store manager.
  • Significance: It served a diverse population of contract laborers from China, Japan, and Portugal, as well as the American and European plantation managers.

Postmarks and Cancellations (The “Town Mark”)

Collector’s value :1887 covers (envelopes) from Hamakuapoko specifically for their unique postal markings.

What is The  Circular Date Stamp (CDS)

​By 1887, Hamakuapoko used a standard Circular Date Stamp.

  • Appearance: A single-line outer circle containing the town name “HAMAKUAPOKO” (or variations) at the top and “MAUI” at the bottom.
  • The Date: The month, day, and year (e.g., OCT 15 1887) were hand-stamped in the center.

​Historical Rarity

Note for Collectors:

Hamakuapoko postmarks from 1887 are considered relatively scarce. Because it was a smaller plantation town compared to Lahaina or Wailuku, fewer pieces of mail survived. A “clear strike” (a perfectly readable postmark) on a well-preserved envelope from the Kingdom era is a significant historical artifact of Maui’s sugar history.

Key Value : Checking mainland bound ships  was a vital daily routine for Hawaii residents reflecting their connection to the outside world.

The Robin’s Collection – Color Study

Modern Hues From Historical Stems

I have been drawn to the beauty of the ephemeral . Once I believed my own existence would simply dissolve like these oxidized blues and faded reds.

Yet I wonder  if we give these colors a name , won’t they live on forever?
