Sean is a piece of art... He's been threatening and spewing shit on people that are doing leather patches everywhere around the internet with the only aim of trying to cut these guy's share and have more order. There was a point in time when every time Miroslav Sekulic would paint a patch, Sean would have the exact same one available 1 or 2 days after that and boast how superior and made in an historically correct way it was compared to any other. He did that for multiple times.
What I find utterly laughable is that Sean was having a fit a couple years ago on FB because the daughter of an AVG pilot, who's now in charge of the association, was threatening to sue him because of copyright infringement. He was boasting that his patch was different than the original one and that, anyway, the design was public property, yadda yadda... And now he's doing exactly the same!
I appreciate people being passionate about what they are doing, especially in the art domain. But if you have to throw shit on other guy's work in the same line of business as you just to try and make yours look better, to me, it speaks volume about you.
