The artist Shepard Fairey also known as Obey the Giant explained that artwork:
"This “Raise the Level (Peace)” print is based on one of my art pieces focused on peace and harmony included in my exhibition at the Straat Museum in Amsterdam. I have replicated many of the textures of the original art piece in the print and I’m very happy with the blend of the painterly and graphic in the print. The phrase “raise the level” encompasses various concepts including raising our level of effort toward diplomacy over conflict, raising awareness about the impacts of burning fossil fuels and the rising sea levels caused by global warming, and the need for immediate action to protect the Earth."
