What did Batman and Wonder Woman each get Superman for his birthday in "For The Man Who Has Everything"?

I have never been able to find the actual comic story, but the Justice League Unlimited adaptation had Bruce getting Clark Cash and Diana getting him a newly created flower called 'The Krypton'.

Different in the comic.

Figured as such.

Batman hired a horticulturalist to breed a new variety of rose called The Krypton. He didn't think anyone else would give him flowers.
Wonder Woman gave him a scale model of the bottle city of Kandor, which had recently been enlarged and moved to a phase world.

Correct (although for some reason, I thought Batman bred the rose himself).

Like Batman has time to breed roses, what with maintenance on the Batmobile, patrolling Crime Alley, and solving complex riddles!

Speaking of that, new question: According to the Riddler, what letter is like death, and why?

Z, because it always comes at the end.

--total guess.

No, but you're on the right track.

Exactamundo, from Batman #263. All yours again.

Don Rickles?
