"

Nudity is generally not permitted on the Australian site, with the following exceptions:

• Media - With regard to media, nudity is permitted to the extent it constitutes a small and insignificant part of a catalog, book, periodical, or other work, which is not, as a whole, primarily devoted to sexual matters. Movies with PG, or R rating and pre-1980 Playboy, Playgirl and Penthouse magazines are permitted, but no photographs depicting nudity are allowed in these listings. Unrated media/movies must state that they are intended for all audiences and viewable by minors."

   

   

  I don't know if the pre-1980 bit would extend to the cards, but the policy on nudity applies to everything and also states that blanking out the "risque bits" on an image doesn't exempt the item from the policy.
