The front design: Captures the powerful moment of the Hawaiian flag being raised on November 28, 1843, symbolizing the return of sovereignty.

The back design: Is a serious conversation starter. Its bold, simple, but the meaning behind it is deep.

Here is the breakdown of the symbolism in that "No 55" design:
The "55": This stands for the 55th U.S. Congress. In 1898, unable to secure the 2/3 vote needed for a Treaty of Annexation (which is the legal way to acquire territory), the 55th Congress passed the "Newlands Resolution" (Joint Resolution 55) instead, which only required a simple majority.

The "Prohibited" Slash : This represents rejection and nullification. By crossing out the "55," the design symbolizes the argument that the 55th Congress had no lawful authority to annex a foreign country via a domestic resolution.

The Message: Its a visual shorthand for: "A Joint Resolution is not a Treaty." It asserts that the sovereignty of the Hawaiian Kingdom was never legally extinguished because the "55" act was invalid.
Its a powerful way to wear your history. It looks like a cool graphic to the average person, but to anyone who knows the history (or asks you about it), its a stand for Ea (sovereignty).
