log.ic Branding Suite
My own branding suite seemed to be a good enough place to start so far as examples of design go. A branding suite would be suited to fit the specific needs of a client. For example, it could include envelopes, web images (such as Facebook banners and social media avatars), and merchandise like tee shirts, hats or pens. The important thing is that your colors and fonts are consistent throughout all your implementation. That's your common thread.
