I posted this on my other blog Threads of Wonder but it really is great to get free stuff, so thought the readers of this blog would appreciate it too. Dover Publishing makes available all sorts of images that have less copyright restrictions. I think this is because of the age of the images. You can sign up for their weekly e-mail of downloadable images which are great for making collages. I have been doing this for a few years and have a nice little collection of them. Go here to sign up for the free stuff!
