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 like this are most commonly made on a copper plate. The artist cuts lines into the plate with a sharp tool to create the image. The process is difficult because the lines must be carefully controlled to show fine details and shading. The image also has to be engraved in reverse so it will print correctly.
