In 2014 artist Jane Kim created a 70 x 40-foot mural at the esteemed Cornell Lab of ornithology called "From So Simple a Beginning: Celebrating the Evolution and Diversity of Birds" (also known as "The Wall of Birds"). It features paintings of all 270 bird species placed on the region they inhabit, and took 2 ½ years to complete. It depicts the 375 million year evolution of birds, all painted to scale.

This set of 50 postcards feature birds selected from the mural and arranged by colour in a stunning spectrum, along with the name and region of the bird on the back. With a 25 vibrant birds repeating twice, these beautiful postcards are perfect for any bird lover.
