This is the Owl Post logo from the Harry Potter books. I got the image from an official journal that was sold around the time Goblet of Fire came out. This was hand-drawn and inked, with colored pencils to finish it.
This image was the one that stolen by another site and caused me to put the watermarks on all my images. What happened was that a Harry Potter forum hotlinked to this image when it was hosted on my old website. They had never asked me for permission to use the image, nor did they credit me. So, I changed the filename and put up a new sketch in its place. The sketch was of someone giving the viewer the bird, and the text was about how I hated when people stole my artwork and didn't credit me. They eventually noticed and took it down. Stupid kids.
