Aeronautical Chart Users' Guide shows an example of a fuzzy magenta line bordering with class Golf airspace. I tried to look but couldn't find any examples on the charts. If you have seen it, please point me in the right direction. Much appreciated!
There is an example in Alaska: the Cape Lisburne LRRS Airport.
As a bonus, note the rare NDB-DME and LF/MF airway (Blue 2)!
