This number plate is on Australia's first home grown car. The Holden FX circa 1948. This car and brand has held fond memories for most of Australia. My dad had an FJ... Now that was awesome. I have no idea how he manged to fit all seven kids in that one :)
This photo was taken at our local shops. I have seen it there quite a few times so I guess the owner is a local. The Holden brand has been discontinued which is a sad day for Australia.
