Usagi Yojimbo DojoBoard

hi friends!
I just found this short interview with stan(and there's also sergio and what seems to be a groo baloonfgure in the background)on the internet.
does anybody know if the cover artwork for the usagi issue with the boss of the red scorpion gang was sold?
enjoy...

This interview was conducted at the Montreal Comics Festival in September. I think I still have that art.
