I'm not considered to be a COG vendor though I do have merch to peddle on occasion. COG does not endorse me for anything, but there is interest in my cartoons on various products such as shirts and mugs. There is no COG logo on this stuff and I am trying to make an obscene profit as I have mouths to feed. With that out of the way, my Cowasaki cartoon is now available on shirts, stickers, and coffee mugs. From S to 3XL.
