Another of my favorites, this early offering from THE SPECTRE 9, April 1969, a 9-page story where the Spectre intervenes to try and save a man who has made a contract with the devil. Story by Dennis O'Neil.

This was in the first few months Wrightson had just turned pro and begun working for DC. Along with his early assigments for SHOWCASE (issues 83 and 84, the latter 2 of 3 issues featuring Nightmaster, if I recall Wrightson's first pro work), HOUSE OF MYSTERY (beginning with issue 179), HOUSE OF SECRETS, WITCHING HOUR, and THE UNEXPECTED. For me this Spectre story was the single best of his early stories.
Also reprinted shortly after in HOUSE OF MYSTERY 224.

Why DC hasn't done a collected edition of the first SPECTRE series (the first issue along with a few prior SHOWCASE issues by Murphy Anderson, issues 2-5 by Neal Adams, and this one-time treat by Wrightson) is a complete mystery to me.
