How would I enlarge/blow up something like this?

It can be enlarged on a regular copier, but it would have to be in sections and then put back together like a puzzle. You could take it to a copy place like Kinkos. They probably wouldn't do it for you , but would show you how to do it yourself. (they wouldn't do it because it is a copyrighted picture) The other possibility is to copy it (on a regular copy machine) onto a transparency and then use an overhead projector to enlarge the image to the size you want and trace it onto a paper.
