Another Worth 1000 contest entry YEARS ago. I don’t recall the guidelines or outcome but I do recall it involved creating a painting out of a newer railway box car.
This was a fun little exercise because when you take 2 different objects you get 2 completely different color pallets and textures. I recall having to take the lady and child out of a painting then make the box car match not only the texture but color platelet. Either way I had fun doing it.
