Ah, DC found a way to squeeze a few more Superman-themed collections in before Best of DC went belly up. It features a particularly brutal cover, too--Bizarro really looks like he's got Superman good, and with all the bad guys cheering it reminds me of that opening scene in Justice. The cover is Ed Hannigan and Klaus Janson, and it's partly due to Janson's rough edge that I think this cover has that feel. Ouch!
"Mxyzptlk Spelled Backward is T-R-O-U-B-L-E" by Martin Pasko, Curt Swan, and Frank Chiaramonte
"The Sixty Deaths of Solomon Grundy" by Steve Englehart and Murphy Anderson (guest-starring Swamp Thing, who when you come to think of it is a great sparring partner for Grundy!)
"Gorilla Grodd's Grandstand Play" by Eliott S. Maggin, Swan, and Anderson
"Target of the Toymen" by Cary Bates, Swan, and Anderson
"The Man With the Kryptonite Heart" by Pasko, Swan, and Tex Blaisdell
"Happy New Year...Rest in Peace" by Pasko, Swan, and Chiaramonte
...the Toyman story is notable because it includes an appearance by a Toyman that looks just like the one that appeared on Challenge of the Super-Friends, a version I thought only ever existed on the cartoon.
