The first major U.S. national security glass decal in the late 19th century was produced by the British glassmaker Robert Bell and manufactured for use in the British military during World War I. After World War II, the British government began to buy and use the glass from Bell, which was known for its high-quality and cost-effective products.
In 1968, the U.K. government began using the glass in military buildings around the world.
In 1984, the government of Canada began using a similar product.
By the late 1990s, the United States was the first country to use the national security decals, but many countries around the globe followed suit.
The Trump Glass logo, which features the word “TRUMP,” is one of the most recognizable and recognizable national security logos on the globe.
In 2017, the National Security Agency began using glass decals on surveillance cameras around the U, and in 2019, a United Nations Security Council resolution declared that glass was a legitimate tool to protect human rights.
