 As the examples above already illustrate, the distinction between autographic and allographic arts is not the same as that between arts that are singular and those that are multiple. Etching, for instance, is still autographic although multiple. Incidentally, this could allow Goodman to account for the interesting hypothesis, advanced by Gregory Currie (1989), of superxerox machines capable of reproducing paintings in a molecule-by-molecule faithful way. Such a cloning technique, Goodman could say, would transform the art of painting from singular to multiple, and yet without changing it from autographic to allographic.
