Regarding image credits

This site started as a personal collection of images which turned into a research project and then this site. By the time I realized I should make a website I'd lost track of the image sources and honestly, it just seemed too difficult to chase them all down much less the permissions for each and every one. Especially from auction sites with anonymous sellers, large corporations, and in some cases, language barriers. I do feel like by this being a research project of sorts, image use falls under "fair use" guidelines but of course I would be happy to credit anyone whose image I have used. My overall goal has been to make the page as a framework for cataloging the Billy Blastoff toy line with collaboration from others so I hope others will contribute information and images for which I will gladly give credit.
