A wonderful example of differing scales - undisclosed - is this 1927
Canadian National Railways map, "Triangle Tour of British Columbia
<https://digital.library.cornell.edu/catalog/ss:19343231>." As Jeffrey
Murray described it:

"This map uses two different scales, but provides no indication as to what
they are or where they meet. The eastern half of the map shows Jasper
National Park (the home of Jasper Park Lodge, which is owned by the
railway) and the northern half of Banff National Park as far south as Bow
Lake, a few miles west of Calgary. The western half of the map, on the
other hand, shows the entire British Columbian coast, from Prince Rupert in
the north to Vancouver and the American border in the south. In other
words, the mapmaker has eliminated the entire southeastern corner of
British Columbia and adjacent Alberta, and filled it in with an enlarged
map of the central portion of the Rocky Mountains. In doing so, the
mapmaker completely eliminated its major competitor, the Canadian Pacific
Railway and its hotel at Lake Louise. The map suggests that the only way
for a visitor to travel the mountains and waters of British Columbia is to
take one of the trains or steamers operated by Canadian National
Railways." Tale
