CONAN THE BARBARIAN (1970) #20

The Black Hound of Vengeance. Facing a threat aboard Prince Yezdigerd’s ship, Conan goes to the Temple of Tarim to slay the black hound! This story was inked by Smith using a Mont Blanc fountain pen in which he wore the nib down inking it. He inked it himself due to the inker having deadline issues. The credits say Dan Adkins inker but that is incorrect. you can read the story in this interview with Smith: http://www.twomorrows.com/comicbookartist/articles/02bws.html
