This is a Brand New, factory sealed Blu Ray set of the BATMAN films from 1989 through 1997:

BATMAN,  BATMAN RETURNS, BATMAN FOREVER and BATMAN AND ROBIN.

It's the original Blu Ray set released by Warner Brothers and comes in its original case as shown.

Batman

Tim Burton directs; Michael Keaton stars as Batman; and Jack Nicholson stars as his arch foe, The Joker. As the Dark Knight, defender of law and order in Gotham City, Batman treads the shadow zone between right and wrong, fighting with only his skill in martial arts and his keenly honed mind to defend the innocent and to purge the memory of his parents' brutal murder-always keeping his true identity as millionaire philanthropist Bruce Wayne a closely guarded secret. Based upon Batman characters created by Bob Kane and published by DC Comics.

Batman Returns

In “Batman Returns” (1992), Oswald Cobblepot was abandoned by his parents as a baby. 33 years later, bent on revenge, he returns to Gotham City as the Penguin. First, he begins a warped campaign to become Mayor, helped by millionaire businessman Max Shreck; next, he undertakes a mission to murder every first-born son in Gotham - a plan which will avenge his own beginnings. Meanwhile, he has two adversaries to contend with: Catwoman, the embittered ex-secretary of Max Shreck, and, of course, the old caped crusader himself.

Batman Forever

In “Batman Forever” (1995), former District Attorney Harvey Two-Face is terrorizing Gotham City, when a new villain appears on the scene - the Riddler. Together they plot to discover Batman's identity, using a device which can probe the human mind. Meanwhile, the caped crusader has been joined by Robin, whose trapeze-artist family have recently been slain by Two-Face.

Batman and Robin

Finally, in “Batman and Robin” (1997), Batman & Robin have to stop the vengeful Mr. Freeze (Arnold Schwarzenegger) from taking over Gotham City by using his new ice weapon.
