Simple Black Key Silhouette

A striking silhouette of a classic key is presented in a dark, solid tone against a plain black backdrop. What makes this design particularly interesting are the unique contours of the key's teeth, which intricately form the distinct peaks and valleys of a city skyline, complete with various building shapes. It's a clean and elegant graphic that cleverly combines two familiar elements into one thoughtful symbol.
