Limited edition metal art pieces include silk screened imagery in the very early stages of the process, which allows for multiple pieces to be made from the same base image. While two metal art works may appear very similar in nature; they are not copies, as the extensive chemical colouring and hand finishing can never be exactly reproduced between any two pieces. In addition to the many finishing artists skilled in the various techniques employed over the period Metallic Design Studio was active (1969-2000); various visual artists contributed original designs (among them: illustrator and graphic artist Dorian Melton).
