Here's two more from Witches' Tales Vol. 2 No. 1, February 1970 (for cover click here). This first bloody little thing, "The Devil's Fiddle," has artwork by Walter Casadei. This is a Eerie Pub. redraw of "The Violin of Death" (Weird Horrors #2, August 1952).
"Horror Harbor" originally saw life in Haunted Thrills #8, April 1953.
Next: "Crawling Death" & "A Skeleton in the Closet." Until then, be good as long as it's both convenient and rewarding. - Mykal
