An enchanting vintage-style illustration showcasing three whimsical sea creatures in festive beach attire, rendered with the same meticulous cross-hatching and detailed pen-and-ink technique. The first creature is a majestic sea turtle with flippers, wearing tropical swim shorts and a sun hat with white brim, the center creature is a graceful dolphin decorated with colorful beach garland elegantly draped around its body and crowned with a starfish, while the third creature is a young seahorse wearing a cheerful coral-colored beach scarf and delicately holding a seashell treasure in its tail. All three sea creatures feature the same expressive eyes, detailed textural work, and charming oceanic character. The artwork maintains identical intricate line work, cross-hatching shading method, and classic beach color palette of ocean blues, coral pinks, and sandy brown tones. Below the sea creature family, ornate script lettering spells out 'Oh Sea, It's Summer!' in a timeless serif font style. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
