The component "911" acts as a noun adjunct (or attributive noun), which is a noun or numeral used to modify another noun. It functions adjectivally to classify the head noun. This structure creates a specific subcategory, distinguishing this type of wallpaper from others (e.g., "nature wallpaper" or "abstract wallpaper"). The modifier "911" semantically narrows the scope to a specific theme, most commonly imagery related to the September 11th attacks, emergency services, or the Porsche 911 automobile.
