Very, I've seen 3-4 (Bowies and big fighters) in total and maybe 20 folders. That being said, the folders bring way more money. The last Bowie I saw was sold about 5 years ago on Ebay, it was sold to Jack Edmondson who does Alamo reenactments, and writes for Blade magazine sometimes. It was somewhat like DE Henry's work in style, with a little more flair.
