This didn't really register until another seller listed 6000 items but there is a duplication in the categories available for antique prints.
We have - Antiques & Art/Art/Prints/Pre 1900 (which has all the appropriate sub-categories and 1361 listings)
and - Antiques & Art/Antiques/Decorative Arts/Prints (which has no sub-categories and 6624 new listings).
These two categories really need to be brought together somehow.
