File:Flash Gordon Excerpt.jpg

Summary

Although this is still under copyright, inclusion here qualifies for Fair Use under US Copyright law because:

It is used for a non-commercial and hopefully educational purpose.
It is representative of the work:

It shows the two main characters, Flash and Dale, along with the primary villain, Ming the Merciless.

It shows the characters in a classic situation: Ming forcing Dale to marry him and Flash trying to rescue Dale.

It also shows Flash (and Thun) evading one danger only to be thrust in to another, a common theme throughout the run.

It is only a small part of the overall work, i.e. an excerpt from a single day's installment.
It should not affect the commercial viability of the copyright (IMHO it should enhance it).
