This was almost certainly not produced by The Aerolux Light Corporation which, according to Wiki, existed from the 1930s through the 1970s.
But bulbs like this are often advertised as "Aerolux style," and one can easily see why.
The Aerolux bulbs could be quite beautiful and intricate. The panoply of flower bulbs below, for example, shows the high level of artisanship that went into their filamentous sculptures.
The patents for the Aerolux bulbs date back to the 1930s.
The bulbs would contain either argon or neon, or a combination of the two.
The little metal sculptures were covered with phosphors. The phosphors fluoresced when excited by "glow discharge."
The phosphors were delicate and could easily flake off and migrate throughout the miniature sculptures, and then certain patches would no longer glow.
The bulbs had a "high yield of light produced versus electricity consumed."
