An Explosion of Joy!
Here is a illustration of a young child looking overjoyed. It was included as part of a set of merit stickers that teachers would award to pupils when marking work.
When I worked as a teacher, I was always really proud awarding one of these to a pupil and seeing how excited they would be to receive one. Eventually, once word got out that I had actually designed them, fellow staff members and even some parents would ask me if they could have one too. An action which proves my theory that you are NEVER to old to be excited by stickers!
