I found these guys about a year ago selling my art on ebay. Contacted them they took it down sold them a new drawing that they could use instead and they are back selling unauthorized image on t-shirts.

Ok they have contacted me I am waiting to find out how this happened

Ok They had an explanation that was acceptable they forgot to proof the ready images and replace them with the images that they bought to replace it.
