I remember one congregation's territory maps used to be copied from an Ordnance Survey map , which is Crown Copyrighted and requires a licence fee to do so. Naughty JW's.
AFAIK, JW congregations don't employ professional map-makers, (cartographers) so how do all the UK congregations obtain such copyrighted items for their business?
Maybe someone will throw some "new light" on this, e.g. former elders.
