The natural follow-up to the recent set union puzzle is this.  Here the clues represent the intersection of the sets in that particular cage.  Each row and column must also contain each of the subsets of {1,2,3} exactly once.

For those unfamiliar with the terminology, the intersection of a group of sets is the collection of elements which are in all of the sets.  For some examples, the intersection of {1,2} and {2,3} is {2} and the intersection of {1,2,3} and {2} is also {2}.
