When two heroes aren't enough

Team-up stories with more than two superhero (or villain) logos on the cover:

 Kid Flash, Aqualad, Robin
(though technically not logos)
1964

 

Batman, Robin, Green Lantern, Green Arrow, Black Canary
(no logos but perhaps because there
wouldn't have been room)
 1972

Batman, Green Arrow, Two-Face 
(the "Plus?", who I'm counting 
even though it's only a tease)
1973

Batman, Wildcat, Joker 
(all three are Bill Finger creations)
1975

Batman, Plastic Man, Metamorpho 
1975

 Batman, Green Arrow, Atom, Joker, Two-Face
(only one co-star logo but the
other three are named and do appear 
more prominently on the cover of 
the next issue [part 2])
1976

Batman, Green Arrow, Metal Men
(as you see, most Brave and Bold issues
with multiple co-stars included Green Arrow)
1977

Batman, Deadman, Sgt. Rock
(the fourth co-star was...
no, not Green Arrow...Sherlock Holmes) 
1978

Superman, Robin, Elongated Man
(also made this list) 
1983

Superman, Joker, Phantom Stranger 
1984

Superman, Firestorm, Captain Atom
(one of the weirder type treatments...
why not just use the existing logos?) 
1986

Superman, Harbinger, Lady Quark, Pariah 
1986

Green Arrow, Question, Butcher
1991

Wonder Woman, Batgirl, Zatanna
2010

Not counting series headliners Superman and Batman, the characters who recur the most: Robin, Green Arrow, and the Joker.

Am I missing any qualifying covers?
