American high school student, Sabrina Brady, won the fourth annual Doodle 4 Google program with her moving illustration of her father returning home from war.

Children in years K-12 from across the United States were asked to use their artistic talents to redesign the Google homepage for the program by illustrating their ‘best day ever’. Google users get to choose the winner by voting for their favourite design from amongst the state finalists selected by Google.

Each child also provides a caption explaining their drawing. This year’s winner wrote: "When I was 10 years old, my dad came home from war. This was my best day ever."
