Here is the cover to one of the last collections of American Splendor with art by Dean Haspiel, one of the last great cartoonists to illustrate Pekar’s unique poetic observations of everyday life.
You can pick up American Splendor: Another Day at Vertigo Comics.
My first look at American Splendor was the first collection, American Splendor: The Life and Times of Harvey Pekar, 1986. That was a breakthrough in comics as it easily became a staple in mainstream bookstores. By 1986, Harvey was already pretty well known through his appearances on “Latenight with David Letterman.”
That book is still around and fairly easy to find. You could pick up a copy through Amazon.
