According to their website, Auckland War Memorial Museum is the only place in the world to exhibit a male and female Tyrannosaurus rex together.
Peter (male) is on the left and is notable as only one of four black Tyrannosaurus rex ever discovered; Barbara (female) on the right is only one of three female Tyrannosaurus rex on record and was gravid at her time of death.
Is there much size difference between the two skeletons ?
I recall a good amount of older media having a factoid that female Tyrannosaurus were larger than males - though this has gotten a fair bit of dispute in recent years.
