Don Martin Steps Out! #D2107

Date given is First Printing. There are at least 11 printings with the D2107 number. On-sale date from 1969 Books and Pamphlets, Copyright Office, Library of Congress.

Could be considered an early Graphic Novel, as it is comics material created to be published in a book format (not originally printed in a magazine or newspaper strip). The same could be said of most of the other Mad Originals (of which this is the first).
