My absolute favorite Carl Barks painting of Scrooge McDuck in the world. It's called "Spoiling the Concert". I love it, in part, because I was able to attend a $140,000 private university, and learn from a magnificent business department, thanks to a music scholarship that paid a giant portion of the bill. It seems so ... appropriate. Alas, they never made a run of rare lithographs, so the only way to get would be to buy it at auction. The last time it surfaced, it sold for a bit more than $155,000. That was in 2007 in Texas.
