This character is loosely based on Indiana Jones, portrayed by Harrison Ford. He even has an embossed scar on his paper chin. Additionally, there is the leather jacket, artifact bag, and fedora.
As for the process, the explorer is all paper sculpture. There is also a miniature yellow light bulb wired behind the torch that actually lights up this cave scene. The background cave paintings, based on Altamira, were accomplished with stencils, sponges and inks. Many dark colored inks were dripped on heavy watercolor paper to make up the cave rocks. This piece is 20" x 16" and about 4 inches thick.
