This section is for cards that have multiple subjects or items where the location is unknown. The multi-view cards will get their own section and I may rename this to Unknown Cards.

The advertising cards now have their own section. The exception to this will be if the advertising is for a company that also has its own page in the Factories section. Seems logical that I would keep all items for a single place together.
