Writer: Marv Wolfman and Mike W. Barr
Artist: George Pérez and Jim Aparo
Publisher: DC Comics (1983)
Includes: The New Teen Titans #37 and Batman and the Outsiders #5
Two issues is not enough to flesh out a TPB, but perhaps DC could convince Marv Wolfman and George Pérez to create a hefty back story to make up the difference.
Or separate stories about different team members teaming up, like Halo and Raven or Black Lighting and Wonder Girl and yes I am a total dork.
Fun Fact: This two shot crossover had a promo poster that I would love to get and frame.
