Query: Utter Drivel

This little tome is a ridiculous, self-congratulatory piece of puffery that may convince two-bit ma and pa businesses across America that they too can think like big ad execs. Bottom line, though, they can't. This book can't teach them how either. It may distract from the initial sense of ill-preparedness small business owners feel when preparing to delve into advertising, but ultimately nothing lies beyond the curtain... Wizard of Oz, anyone?
