The painting, which features Ross' signature "happy little trees" surrounded by a body of water, "is the most historically significant Bob Ross original painting ever created," the auction house states on the painting's listing. "It is exceedingly rare to find any Bob Ross episode pieces, and this is a one-of-a-kind opportunity to own the very first one," it added.

Ross' show, where he taught viewers how to paint detailed landscapes, aired from 1983 to 1994. Throughout his career, he made about 30,000 paintings, per Modern Artifact, until he died of lymphoma at the age of 52 in 1995.

“开车force behind the increased demand for Bob Ross paintings seems to be collectors themselves," Modern Artifact owner Ryan Nelson said in a statement, perCNN. "Nostalgia, social media, and an increased interest by the general public in the personality behind the art have all contributed to his current popularity."
