I've created the following two items:
The sailboat, above, I found on eBay and subsequently on Amazon. It fits perfectly on the boat/rocket frame. The mast for the sail can be inserted into the boat. The boat is wood and does float. This is a recent build.
Mint car with shredded money load. The car is the KC Fed Reserve. The attention to detail part: The shredded money is also from the KC Fed Reserve. Car and money found on eBay. I built this earlier this year.
