A comic book cover featuring the classic 'Superman' logo prominently displayed at the top and the title 'Merry Christmas' written below it in festive lettering. The cover showcases Superman, wearing a fully red costume inspired by Santa Claus, with a white 'S' emblem on his chest, a red cape with white fur trim, and a Santa hat. His red cape is creatively used as a sack, bulging with brightly wrapped presents peeking out. Flying beside him is Krypto, his loyal white Labrador Retriever, depicted as Rudolph the Red-Nosed Reindeer. Krypto has a glowing red nose that shines brightly, faux reindeer antlers tied to his head with a string, and a red cape matching Superman's. He also wears a golden collar with a Superman shield-shaped medallion featuring the 'S' symbol. The background is a vibrant night cityscape, with glowing lights, gently falling snow, and a cheerful holiday atmosphere, all styled in a classic comic book aesthetic.
