A very cool Australian map.
It is just a really nice map card with even two trains involved :)
The one in the top right corner was issued in 2009 in a set of 8 stamps depicting Corrugated Landscapes, where on this one a Traditional Home is portrayed. The 50c under it is from 2002 from a set of 3 stamps called Panorama, with this one showing Walker Flat.
The seals' one is also from 2009, from a set of 5 stamps from an Australian joint territories issue depicting Species at risk. This is the Subantarctic Fur Seal.
