Story by Lee Falk. From the Return of the Sky Band story. Sky bandits Sala and Margo chatting up the imprisoned Phantom. In my view, Ray Moore is the greatest Phantom artist ever without any serious competition, and definitely an underrated Golden Age strip artist. Unfortunately his career was cut short because of the wounds he was inflicted with in WW2.
The guy I bought this from many years ago told me that there are only seven known complete Moore Sunday original pages in existence. I don´t know if this is correct, but they are very rare indeed.
