Query: A signature invariant for knotted Klein graphs   We define some signature invariants for a class of knotted trivalent graphs
using branched covers. We relate them to classical signatures of knots and
links. Finally, we explain how to compute these invariants through the example
of Kinoshita's knotted theta graph.
