Brand new and sealed DC Universe Super Heroes Lego set 10937 - Batman: Arkham Asylum breakout. The box is showing signs of storage wear and the seals on one end do appear to have slipped (possibly when hot and lifted by the flap). This set retired in 2014 and is hard to find. There are 8 mini figures included - 5 of which are unique to this set. SH048 - Batman with black wings and white headband.
SH059 - Robin with black hood and cape. SH061 - the Joker with prison jumpsuit with belt.
