This is a Chronological list of parody covers of the National Geographic Magazine. Scott Shier has an excellent discussion on this topic in the Ephemera & Collectibles group. I felt that since these covers reflect an outside perception of the magazine I would provide a visual listing over time of these covers here to maybe provide some insight into how others see us.
Note, I am not only including actual covers and pages simulating covers in this listing but also posters, refrigerator magnets, trading cards and electronic images.

Thanks Tom for adding these here in-group! Of course my fave is still always Snoopy & Beagle.
Also, I think I recall you mentioning the Dr. Fegg's one, but for the moment, I feel like that's the first time I saw it, in detail.
Dr. Fegg is the creation of Terry Jones and Michael Palin, both from Monty Python fame. Here is his portrait:
