This reminds me of the work of Jasper Johns, whose use of commercial stencils transformed ordinary and commonplace shapes and symbols into works of art. Jasper Johns is probably most well known for his American flags, but in the 1950s he started using stencilled letters and numbers as the basis for his paintings, prints and drawings. He produced many variations of numbers: single numbers, grid patterns of repeating rows of numbers, superimposed numbers. He was interested in exploring the ways we see and why, and his work has certainly made a difference to my view of the world around me.
