Giving back ownership

Still researching these weird, cheap, "artsy" pillows that are made overseas and sold all over the internet. I feel like I'm writing a thesis on design theft. I don't know how many people I've emailed asking if their designs are being used legitimately.

In an attempt to start looking for solutions (I really get sucked into the matching game of artist to design), I decided to look at one shop on etsy. I compiled an image of all the pillows they offer and I blacked out the designs of artists who I suspect didn't license their designs to be sold on these pillows.That's not to say all of the other pillows are legit, there are some that are from books, others that are from major brands like Tannoka and Paul Frank, and those I couldn't place with a simple reverse image search. The shop owner probably doesn't know they're selling counterfeit goods, but odds are good they know they're not within etsy selling guidelines.

Below are the artists whom I've been able to assert design credit. The ones in bold are the artists I've confirmed did not license their design for use on these pillows being sold.
