Design a vintage-inspired Halloween t-shirt featuring a central graphic of a carved pumpkin surrounded by playful ghosts and whimsical bats. The pumpkin is realistically rendered, showcasing intricate details of its face, while the ghosts appear soft and ethereal, floating around it. Above the pumpkin, the phrase "Happy Halloween" is elegantly scripted in a vintage font, colored in a bright orange that contrasts beautifully against the black fabric of the t-shirt. The background remains minimal, allowing the main elements to stand out, creating a festive yet spooky atmosphere that captures the essence of Halloween.
