Wizard magazine characterized
Keyhole as featuring "such a wide range of short stories, from travel strips based on Neufeld's journey through Asia to Haspiel’s wonky superhero 'Billy Dogma,' that every issue feels like an anthology," finishing its review with the assessment, "Haspiel’s stylized black-find-while art contrasts nicely with Neufeld’s earthy cartooning to make for a consistently good-looking comic." Similarly,
The Comics Journal reviewed
Keyhole this way: "Brought together in a single, independent magazine, these artists' strong, disparate talents create a broad reading experience, and a blending of artistic intentions and personal expression like very few others available today in American comix". Haspiel debuted his existential antihero, Billy Dogma, in
Keyhole, a character whose adventures have since been published by Modern Comics, Top Shelf,
Alternative Comics,
Z2 Comics, and
Image Comics. In addition, Haspiel collected many of the autobiographical stories from
Keyhole in
Opposable Thumbs (2001), published by Alternative Comics, and used those stories as a jumping-off point for the
Street Code stories he later told on
DC Comics'
webcomics imprint
Zuda Comics. Neufeld, in turn, collected the "Titans of Finance" stories in a self-titled comic published by Alternative in 2001. In 2004, he collected his
Keyhole travel stories (as well as subsequent ones) in the
Xeric Award-winning graphic novel
A Few Perfect Hours. In addition, both cartoonists became regular illustrators for Harvey Pekar and his
American Splendor projects. == Notes ==
