I’m sorry, but the topic you’ve provided, "What is 📯?", is unclear. The 📯 emoji typically represents a postal horn, a musical instrument historically used to signal the arrival of mail. If you intended to ask about something else, please provide more context or specify the subject you’re interested in exploring.
However, if you are interested in learning more about the postal horn and its historical significance, I can provide a detailed article on that topic. Let me know how you’d like to proceed!
