I have a small book called "Moche Pottery from Peru" by George Bankes it mentions earlier similar pots from the Cuspisnique period and also says that this style of pot was made for around seven hundred years and identifies five different phases so there is plenty of scope for variation of quality.

The most unusual thing about the example above is the lack of decoration. The Moche never developed the fired glaze so this might just be an example where any colour hasn't survived.

I'll have a look at my photos from the Peruvian Museum and see if I can see anything similar.

The British Museum examples some of which are now back on display after being hidden for many years are all very fine examples and all decorated.
