This is how mail used to get delivered around Australia, a long long time ago.
http://www.loadeddoghotel.com/asset...0Co_0004.jpgMy dad owns this cover which was sent by his mum, it went on the only re-run of a cobb & co carriage, a long time after these carriages stopped delivering mail, one went around Australia delivering mail as a memorial for cobb & co. that's how dad's mum sent it to dad, and now he has a cover from it, even stating on the front what it was from. Don't know where it is at the moment so I can't post pics.
Steve do you know anything?
