Create a bright and dynamic NFT-style illustration of an elderly person with white hair, wearing large sunglasses, and a bold striped blazer over a shirt with a bow tie. They are adorned with colorful chunky necklaces and are giving a thumbs-up gesture. The background is a solid bright yellow. The character is outlined with simple lines for a playful and cartoonish look, and the textures are soft and approachable. The style should be unique, suitable for a digital collectible.
