The Telegram is an item in the SNES and PC releases of Mario's Time Machine. It is given to Mario by a telegram office's worker, who mentions that he is interested in collecting Postcards from across the world. Once he receives a Postcard from Menlo Park from Mario, he continues to talk about the local inventor, Thomas Edison, and asks Mario to deliver the Telegram to the local druggist. The pharmacist also mentions that he is waiting for a telegram from his brother (who is working with Edison on his inventions), and refuses to talk further about Edison until he receives. After the Telegram is delivered to him, he reads its contents out loud to Mario, detailing how Thomas Edison is close to a breakthrough with the incandescent light bulb, paving the way for new innovations such as electrical power plants and motion pictures. The druggist then mentions that a Football crashed through his window, and as he has no use for it, he gives it to Mario.
"EDISON NEAR BREAKTHROUGH ON INCANDESCENT LIGHT BULB. STOP. STILL NEEDS TO FIND RELIABLE FILAMENT THAT GLOWS WHEN ELECTRIFIED IN VACUUM. STOP. EDISON CERTAIN CARBONIZED BAMBOO IS THE ANSWER. STOP. ONCE DONE, WE CAN START WORK ON FIRST ELECTRIC POWER PLANT AND MOTION PICTURES. STOP. BE BACK SOON. STOP. YOUR BROTHER."
