Portfolio of landing pages

How can I create a portfolio page of landing pages I have written the copy on? Are writers taking screenshots or is there a way to replicate the landing page?

There are ways to embed a site within a site, but many sites will restrict that to prevent clickjacking. (You should for your site as well. Settings=>Advanced=>Website Protection) Embedding also doesn't give visitors the best experience, in my opinion, especially if you're doing a scroll within a scroll.

I would suggest taking a screenshot and adding it as an image, with or without a link to the page in question.
