For those about to rock, we have found the perfect agency credentials kit.

In this sixth installment of Adweek's ongoing series on new-business materials, we present perhaps the most streamlined, conceptual kit thus far: davidandgoliath's "one shot" mailing. It consists of a simple burlap pouch containing a single rock imprinted with the shop's name and Web address. Nothing fancy. Nothing complicated. Just a literal manifestation of the Biblical story from which the agency took its name. The Web site does the rest.

Elsewhere in this batch: a humorous Osteo-BiFlex case study from Cramer-Krasselt that takes the form of Frankenstein's diary (complete with existential musings and notations about drink dates) and an invitation from Boone/Oakley to fill out a Mad Libs-like letter.

Bernstein-Rein and Saatchi & Saatchi round out the group, deciding to go with somewhat more conventional approaches.
