Besides Scrooge himself, I'd probably have to say either Magica or Glomgold. Although I really love Goldie but Barks only used her once and he only used Glomgold 3 times I think. My favorite Glomgold story is The Second Richest Duck. I'd say Back to the Klondike or Tra La La are probably my two favorite Barks stories but choosing the best Barks story would be like trying to decide whether Jennifer Aniston or Grace Kelly is more beautiful than the other. LOL! My favorite Rosa story is The Incredible Shrinking Tightwad and probably my favorite character that Rosa used besides the main characters is Angus McDuck. I loved how he acted like the consummate tough guy but was really kinda bumbling. I have a sketch of him from Don. I also have a sketch of Scrooge from his Christmas On Bear Mountain cloak, a sketch of Fergus and Downy, young Scrooge, Glomgold, Gyro, Scrooge in his MS River sailing outfit, and Blackheart Beagle. Of all Don's prints from his convention booth I have them all but maaaaaaaybe 10 or 15 but it's mostly because the ones I've yet to collect are featuring Donald. I'm way more of a Scrooge fan. The stupid virus shut down the conventions this year and I had was getting Don this Only A Poor Old Man shirt that I have but I won't get to see him again until next year hopefully. IF you're a legit "Duck fan" he'll be super awesome to you. He has given me TONS of free prints over the years. If you're NOT a legit Duck fan and only know about Ducktales I've seen him be seriously cantankerous to people and even little kids.
