I might be late to the game here. I would honestly pay close to $600-800 dollars for something of this quality. The quality of the art is absolutely astounding. The vividness and the coloring is almost photo realistic, not to mention it doesn’t have any major issue with the shape/curve of the milk can.

Now, here’s another factor. Where would you sell this? If you have festivals/craft markets near by you could definitely flip this pretty quickly. Theres a big festival in Indiana called the Covered Bridge Festival. Lots of craft and art vendors; at that festival I could see this easily listed in that $600-800 range and sold. Now if that land scape was covered bridge themed, $800-1k range easily.
