Spur is the Baltimore-based firm of David Plunkert, a product of the glory days of the design program at Shepherd College (Now a University) in West Virginia, where I attended school. David takes a highly conceptual, illustrative approach to solving the design problem, and his unique technique has made him one of the most well-known and most often copied (ripped-off) designers in the world. His work has has been recognized in design annuals 100s and 100s of times over the past 20 years. Be sure to check out the Spur site, as well as David's Illustration site, linked at the bottom of the page. You are sure to recognize his collage style.
