Cars, Cars Cars. We all love them. This grayscale AND sketch coloring book is filled with pictures of automobiles that once were shiny and bright. Whether you color Grayscale or Sketch, or you want to do both 'Rust Buckets' provides each. Colorize cars that have seen better days. My photos capture cars in their decline. Rusted, sitting in a field, or ready for the junk yard. Rust Buckets is the first in my 'MAN'iac series that focuses on cars, hot rods, classics, military, boats, trains and planes and machinery. It is family friendly! So whether you are a gear head, a budding colorist, an experienced colorist or you just like a variety of different types of coloring books the Maniac series fills the bill.
