I also wonder how the defendant attained the image if the artist had never licensed it - clearly it's a theft but to print it on hang tags of jeans the image must have been "printable" and attained via the Internet (an assumption of course). I wonder how (if at all possible) that sort of thing could have been prevented.
For example, supposing the jeans were sold in, say, Russia. The artist would never have known I would think.
Cheers,
