Watching Museum Diaries early this morning on TVO and I noticed a word they used when talking about fakes and forgeries, pastiche. It is interesting how fakes have become their own genre. Antique fakes can be as interesting and historical as the real artifacts. Also, there is still the danger of being wrong and deciding an item is fake when it is not. Some artifacts are just created differently from the standard at the time. People could be innovative hundreds and thousands of years ago too. So, a different colour, style, etc, is not a sure sign of a forgery or fake.
Wikipedia - A pastiche is a work of visual art, literature, theatre, or music that imitates the style or character of the work of one or more other artists. Unlike parody, pastiche celebrates, rather than mocks, the work it imitates.
