Create a fictional webpage design for ‘igotchu.com’ featuring a T-shirt for sale. The T-shirt displays the tall, hand-drawn illustration of Denver, a T-Rex, skateboarding in a concrete skatepark with neon graffiti. The webpage should have a modern, e-commerce style, showcasing the T-shirt prominently with the Denver illustration. Include elements like a product description, price tag, and an ‘Add to Cart’ button, making it look like a real online shop. The design should be clean, professional, and appealing to potential buyers."
