Happydale was Seth's first full-length comic book, actually a two part series, some 140 pages in all, entirely drawn on spec, and then sent to Vertigo, the more edgy, risk-taking division of DC Comics.  They bought it complete, and, as they say, the rest is history.  
This is the wraparound cover for part two, in which the swat team and the Happydalians assemble for a stakeout-cum-county fair at the home of Mrs. Merryweather.
