Walking into Museum Station is just like walking into a museum of the era in which it was built. The walls along the platforms are lined with advertisements from that era:
Top: Arnotts Until just a few years ago, Arnotts was an iconic Australian company producing biscuits. There are signs similar to this in some quite striking spots all over Sydney. One that comes to mind, is on an overpass on Parramatta Road, just after the start of the motorway at Concord.
Bottom left: MorteinWhen you're on a good thing - stick to it! Even today, swatting flies is known as "the great Australian wave".
Bottom right: Orient Line From Australia to London for less than three farthings a mile. Australia is an isolated country very far from The Home Country. This was the era of Sir Charles Kingsford Smith. Qantas was just being established in the backblocks of Queensland.
The mid-month Subway theme has contributions from the following cities:
Budapest - London - Paris - Stockholm - Sydney
