A poster for "The Mummy's Secret" unfolds in the style of a '70s mommy-on-the-phonecore, drawing heavily from B-movie aesthetics with a rich palette of crimson and earthy browns. It channels the distinctive framing of vintage Marvel comics, with comic strip borders enclosing dynamic scenes that explode with color and action. The visuals are steeped in carpetpunk sensibilities, evoking a retro-futuristic vibe with intricate tapestry-like designs in the mummy's attire and the tomb's decor. Grotesque, exaggerated characters with wide-eyed expressions add a layer of eeriness, while dimly lit hieroglyphics and ancient artifacts peek through the layers, creating a mysterious and sinister allure.
