“See you over the rainbow” represents hope. Rainbows show after rainfall when the sun peeks through the clouds. Which can be interpreted as after a bad time (the rain) there is a good time (the sun) which forms a rainbow. Drawing a rainbow was a way of expressing this hard time. By looking at a rainbow many people think of different things, I see hope, because I know everything will be alright. Seeing a rainbow can make someone smile because of how pretty, bright, and rare they are. These would/could be hung on the windows inside homes. Therefore, when people pass they could see the rainbows on the windows and smile. They could also be hung up on fences and doors.
