Maryborough is the town where P.LTravers, the woman who wrote Mary Poppins was born. So they have a few Poppins bits and pieces around the place. The town used to be a major port at the beginning of the 20thC, but is now a pretty small place with some lovely old buildings and pub grub.
These little gems were for sale at the local market. They are holograms. They are framed. There are dolphins. Need I say more?
