A few months back I was selling Gotham PD folder sets and Joker cards on eBay. Some time after I stopped selling them I remember sending someone a zip file with all the files I'd collected, over 120 of them that took me months to collect and manipulate, which I just found on eBay.
The Dark Knight - Digital Prop Collection
The seller, "dstruzan" is offering just those files and he's even using one of my old auction pics to sell them. Unfortunately, my auction was too long ago and doesn't appear when you click on it which just proves this guy kept the pic from my auction and has been saving it all this time.
