These t-shirts have been screen printed to celebrate the near completion of the long awaited Oiseaux de France, following the pochoir layers that Peter uses in the book.

The images in Peter's Oiseaux de France are made with stencils, or pochoir in French. The process has a history that can be traced back to medieval France and has generally been used as a means of adding colour to black & white woodcuts. In this book the images are made without any printed outlines; the acrylic colours applied in up to eight separate layers describe at once the shapes of the birds and the colourful detail they contain.
