since there are burgees on the mytical 3rd mast and one on the 2nd mast. look up the mytical burgees, compare to real burgees and that my get you to a country. however they could also be mythical as well.
if the burgees are real. then that detail of the mytical image is real and the boat may have real origins. if the burgees are not real, then much of the detail must be suspect. That will determine if its Alice or the Mad Hatter down the particular rabbit hole.
it appears to be an artist rendition of a 3-masted junk conversion, however since the bow is square, the stern is not, I assume there is more than a bit of artistic licensing on the vessel.
Happy hunting and seasons greetings.
