The unveiling of the 50-star flag took place in Philadelphia amidst Independence Day festivities, representing a significant milestone in American history. Following Hawaii's admission as the 50th state on August 21, 1959, the completion of the new flag symbolized a unified nation. The 50-star design was officially adopted on July 4, 1960, taking almost ten and a half months after Hawaii's statehood for the flag's public debut. This event was celebrated with a grand ceremony that included a parade and various patriotic displays in the city known for its historical significance in American independence. Philadelphia, having served as the birthplace of the nation, was a fitting venue for such a historic occasion.

During the ceremony, the new flag was hoisted and showcased prominently, replacing the previous 49-star version. The event was a moment of national pride, highlighting not only Hawaii's inclusion but also the evolving nature of the flag as a representation of the states that make up the Union. Patriotic speeches were made, emphasizing the significance of unity and diversity in the country.

The day was filled with celebratory activities, which included music, dance, and various forms of entertainment, drawing large crowds eager to witness this piece of history. The new flag had a bright design with five rows of alternating six and five stars, a visually striking representation of the states and a source of inspiration for many citizens as they embraced their national identity in light of new statehood and changing demographics.
