I sent them an email just to tell them I made the artwork and ask if they've sold much just because I'm naturally curious, plus giving them my blessing to keep using it if they want.
I don't need a decal set because 1) I don't have the machine anymore and 2) if I needed some decals, I've already proven I can make them myself.
They replied and didn't offer any guesses as to how many they've sold (maybe zero yet) but did say they got the artwork off some CD somebody gave them. So if that's true, and I don't have any reason to think otherwise, then they didn't just lift the art off my site and start selling them. And on my site I even mention that the files are free for the taking, so I wouldn't care even if they did that.
I don't mind that they might be making some money off it. I do something else for a living - selling decals isn't my "thing". More power to them. Too bad they apparently fell through delivering a set to the guy Strangeways referenced. My art is still there for the taking if somebody wants to make their own and if somebody would rather just buy a set already made, now there's a source to do that too.
Between my TZ apron cards and those drop target decals I'm slowly becoming a mini-pinball artist
Too bad it takes me about six hours per square inch to draw the stuff up, hehe. I can realize an end result that starts out in my head, but I have zero art technique so it's painfully slow. I guess it's just nice that all that time ends up being displayed in more than my own single machine. If it goes into a half-dozen machines, then I'm down to an hour per square inch. Getting better.
