Sandra of the Secret Service

First appearance: New Fun #1 (February 1935)


Initially, the feature was about one page and not in full color:

from New Fun #1


from New Fun #2 (March 1935)

For issue #7-8, the comic book was retitled "More Fun", and Sandra's feature became a full page. With issue #9 (cover-dated March-April 1936), the title was expanded to "More Fun Comics" and Sandra's feature was expanded to two pages.



With issue #13, the feature expanded to three pages, and it kept that length through issue #35 (September 1938), it's last appearance.




Despite the "To Be Continued" at the end of that episode, it does not appear it ever was.
