Marvel - Uncanny X-Men #6 (1964) Sub-MarinerUncanny X Men #6 Published 1st July 1964 The X Men and Brotherhood are evenly matched, and both teams think Namor the Sub Mariner can turn the tide in their favor! Too bad no one told them that in the war between good and evil, Namor's just as likely to fight both sides! 3. 5 Grade An average, second hand, obviously read copy with marks and minor defects but still respectable and appealing. Printing lustre almost gone but not soiled or heavily stained
