Answer the following question in 3-4 complete sentences. What type of surface is most commonly used for engraving pieces, such as the one above? Why would the process be difficult?

Answer:

Engravings are most commonly made on a smooth copper plate. The artist must cut many fine, precise lines into the hard metal, and mistakes can be difficult to correct. The detailed clothing, face, and shading in this image would make the process especially painstaking.
