I need a digital image of an antique map (ideally of England/the British Isles) for a piece of artwork. I have found various not-quite-right things on stock image websites. The sort of thing I want is the kind of image antiques dealers display on their websites as an example of their stock, but I am uncertain of the copyright status of those images. Where can I find such an image and be sure that I am permitted to use it?
