"Collateral" is a word that covers a wide variety of business and creative materials, from full campaigns (signature brochures, letterhead, advertising and promotional mailings) to specialty items and web site layout.  Here are a few examples of collateral projects, often involving multiple items and full branding, that I've had the pleasure of working on in the past few years.
