What the heck, one more. Wrightson's "Secret of the Egyptian Cat", from HOUSE OF MYSTERY 186, May-June 1970, a 10-page story. Wrightson's 14th published mainstream story.

It was tough to find by itself, this link is where someone published the entire contents of WELCOME BACK TO HOUSE OF MYSTERY, July 1998, a DC editor's pick of her greatest hits from DC's early 70's mystery titles. And while not exactly my pick, is still a good selection. In particular, Wrightson's "Secret of the Egyptian Cat" (on page 37).
And Neal Adams' "Nightmare" (on page 25), both of which are from HOUSE OF MYSTERY 186.

Jumping the gun in my chronology a bit, it also reprints "The Gourmet" from PLOP 1, Aug 1973 (on page 9), 6 pages.
Wrightson's 33rd published story. And won an ACBA award for "Best Humor Story" for 1973.

And "Molded In Evil" from PLOP 5, June 1974 (on page 87), also 6 pages.
Wrightson's 40th published story.

Plus several intro pages by Wrightson from House of Mystery 203 (inside cover), June 1972.
And an intro page from HOUSE OF MYSTERY 219, Nov 1973 (used as contents page in this version, with new text).
And a new 1998 cover by Wrightson, roughly 20 years before he died.

You can see in the contents of this collection how much his art evolved from 1969-1970 up to 1972-1974. From talented amateur to grandmaster.
