Even though the concept behind neon signs dates back to discoveries made in the 17th century, the first neon signs became known to the public at the beginning of the 20th century. These signs were first displayed in Paris, but they were introduced in the United States soon afterwards. Collecting vintage neon signs is a popular activity among individuals interested in the history of urban landscapes. Those attracted to advertising and lighting collectibles are also inclined to appreciate the bright lights and colors of a neon bar or beer sign.

Neon signs have been popular fixtures in outdoor advertising ever since they first came to view. Neon, a rare gas present in the atmosphere, was discovered in 1898. To make neon signs, hollow glass tubes are heated and shaped, and then filled with neon gas, which glows with a characteristic red light. However, despite their name, neon signs do not only contain neon gas fillings.

The bright lights and colors of neon signs are visible during daytime and are impossible to miss at night. The first neon signs featured few color possibilities. Blue, white, and gold color were among the first colors discovered, by mixing different substances like mercury and helium. Nowadays, following the introduction of fluorescent powders, more than 150 colors are possible besides the original red.

The cost of a neon sign is not associated with the materials used but the labor involved in its making. Collectors of neon signs are usually attracted to restored original signs. Since the life span of a neon sign is often under 15 years, obtaining the colors originally featured by an old sign usually entails a process of restoration. Fortunately, in most cases, neon signs can be repaired and recharged, regaining their original glitz and glow.
