Comic book expert (and comic book writer, and television writer, and blogger, etc etc) Mark Evanier corrected obituary articles that used Flash #165 as an example of the late artist Carmine Infantino's work. Evanier said that it's one of the few covers of that era that Infantino did not draw -- he may have had some involvement in the sketching stage, but if it were signed, Murphy Anderson would have signed as artist.
Readers responded that the cover actually is signed by Murphy Anderson. Can you find the signature?
I recommend Mark's blog, which is a lot of fun, and one of my daily stops.
