I kept doing another one each year until 2007. The original intention was as promotional cards; I saw and read that other illustrators sent out promotional cards to clients and prospective clients, usually on the obvious holiday. Well, Halloween has always been my favorite, so why not avoid the Xmas mail glut as well? I did try it as promotion, made a list from various sources like the Artists Market ( do they still publish that? ), but didn't get *any* nibbles. I doubt that direct mail even works any more these days. Marketing is obviously a weak point with me.
Why did I stop doing these in 2007? One reason was that I ran out of ideas, or had ones that were too similar to the Nightmare Before Xmas, which also often fused the two holidays.
I've been meaning to print these to sell as cards (they can work for both holidays!). I printed a small run for Fool's Mansion in Salem, MA, an obvious place to sell them. When I was there recently there were only four left. Wish I could've afforded to print more. Another Kickstarter possibility?
