What looks like highly meticulous animal carvings are actually multi-layered paper sculptures, created by a Canadian artist Calvin Nicholls. Working on them since 1986, the artist spends from 4 weeks to 2 years on a piece. Before starting the work, Calvin researches the animal to get the musculoskeletal features correct in his drawing. A final drawing becomes a pattern for the pieces that he cuts out with scalpels and x-acto knives. He then assembles the pieces together and uses carefully set studio lighting to get the effect of depth.
Calvin has produced over 500 pieces, which were widely exhibited throughout North America. The artist is very open about his method and encourages more artists to try it, so check it out on his website!
