Floppy Friday: Volume 2 Issue 4 addendum
A sample of the additional material in issue 4 of the Girl Genius comic book: Old ads for Girl Genius merchandise and Cheapass games that are no longer available, at least from the sources given.
When @leletha-jann reblogged my original post about issue 4 of the Girl Genius comic book, one of the tag used was "WHAT was the ten pages bonus content?"
"Bonus content" wasn't the best way to categorize the extra material - additional content is probably more accurate. This issue of the comic starts with "Our story thus far", a summary of the plot up to this point by Kaja. After the comic is a two-page letters section, a page of ads, two pages of fake ads ("Exciting New Products for the Working Mad Scientist" written by Jeff Vogel and illustrated by Phil), a very old sketch by Phil, a report "On the Status of the Americas: A Clarification for General Distribution" by Boris Vasily Konstantin Andrei Myshkin Dolokhov, Secretary to Baron Klaus Wulfenbach (probably noncanonical and not very informative), and the Girl Genius Secret Cypher Society coded message for the issue, along with a form to subscribe to the comic book.
This is typical of the additional material in most issues of the comic book: letters, ads, old or additional art by Phil and others, material written in an in-universe style by the Foglios or their friends and minions, and a secret message page.
The Foglios included a notoriously complex do-it-yourself Girl Genius decoder wheel on the cover of Girl Genius comic book issue 0, The Secret Blueprints, which I haven't included in my series because it is available as a PDF from DriveThru Comics. Alternatively, you can get a downloadable high-resolution PDF of the code wheel from an old Fun Stuff page that is still available on the Girl Genius website (link below), that you can print, cut out, and assemble.
The Girl Genius Cypher Society
This page also includes all of the secret messages from the comic books and a handy online decoder, if you're impatient.
Another sample: a sketch by Phil from 1978! (If I am reading his handwriting correctly.)
