London-based illustrator Hattie Stewart drew 'Doodle-Bombs' on the cover of a fashion magazine and became known to the public, winning the ADC Young Gun in 2017 given to outstanding art directors under the age of 30. Its popularity has soared with its cheerful, bright, and happy icons, and it is conducting advertising campaigns and collaborations with leading global brands, including magazines. Her work, avoiding more traditional illustration styles, is bold, entertaining, and experimental in applications.
