The document provides details on the development process of logos, posters, and merchandise for a social action campaign. It includes sketches, digital designs, and explanations of design choices. For the logos, the designer experimented with different styles and characters before settling on a crab mascot. Posters were created to educate children about litter in an engaging way. Merchandise included t-shirt, hat, and bodyboard designs building on the established logo. Membership forms were also designed, incorporating the mascot character into underwater scenes.
