Is there a way to keep archive of front pages?

I run a community news site. I’d love to be able to preserve each week’s front page, with links and images intact, in an archive. In other words, if you want to see what was happening in our town on March 12, 2009, you could see the front page as it looked back then, and click through to read the articles.

I can’t find a plugin that would do this. Any ideas?
