Category:Incorrect dates from the Fleuron database

As the 'Fleuron' database from the w:en:Cambridge University Library is automated, some dates are misinterpreted.

This category should be applied to images when they have been correctly filed under the appropriate category in category:fleurons by year but contain a link to the database which has not yet been corrected (the maintainers can be emailed with errata), and applied to categories of type "category:YYYY fleurons" if no fleurons can have been published in that year (for example, the year is in the future). Where an incorrect year category can be traced to a single correctable error, the category should also be soft- or hard-redirected to the real year category that contains the offending image.
