A whimsical, pastel-toned illustration of a family on a beach with a narwhal, acting as a book cover titled "Seven Go on A Seaside Adventure."

A whimsical, pastel-toned illustrated book cover in the style of an Enid Blyton novel. Title at the top: “Seven Go On A Seaside Adventure” in vintage serif font. The scene shows seven family members on Swanage beach, Dorset, with Ballard Down in the background — a green cliff rising behind the sandy beach. Five family members (a mother aged 66, daughter aged 30, son aged 30, man aged 30, and daughter-in-law aged 30) are sitting on a blue tartan picnic blanket. On the blanket is a vintage camera and a picnic basket with a bottle of wine poking out. One older man (father) is asleep in a striped deck chair nearby. Another man (aged 35) is swimming in the sea. A funny cartoon-style octopus pops its head out of the water, and a white narwhal leaps joyfully nearby. A small white yacht sails in the distance. The illustration should be light, nostalgic, and full of charm, using soft pastel colours and a hand-painted look, like a 1950s children’s book cover. See more
