1st appearance of the Shade-Thralls, humans who serve the Dweller In Darkness

⚠ Misconception: many claim that Wolverine is first seen in an advertisement for The Incredible Hulk #181 printed in Thor #229 and Daredevil #115. These issues did not go on sale prior to the publication of Incredible Hulk #181. Comic Reader #109 reports the on-sale date of Thor #229 as August 6, 1974. The on-sale date of The Incredible Hulk #181 was July 30, 1974 which was the same day Daredevil #115 went on sale. Regardless, Wolverine was officially first seen in print briefly (cameo) in The Incredible Hulk #180 (July 2, 1974). Advertisements and preview excerpts are not considered official first appearances
