Superman Vol.2 #73 (VF/NM)
Liri Lee pays Superman a visit at the Justice League headquarters, where she almost gets shot at by Booster Gold, fearing that she's coming to take him back to the 25th Century like the last Linear Man tried to. Liri Lee reveals that her purpose of coming is to warn Superman of Waverider, whom the Linear Men see as an unstable element in the timestream that they are so vigilant to protect. Before Superman could ask anymore about Waverider, Liri Lee vanishes.
