We analyze 13.8 \rm fb^{-1} of the integrated e^+e^- luminosity collected at10.6 GeV center-of-mass energy with the CLEO II and CLEO II.V detectors tostudy exclusive two-photon production of hadrons with masses below 1.7{\rm \GeV/c^2} decaying into the K^0_S K^\pm \pi^\mp final state. We observe twostatistically significant enhancements in the \eta(1440) mass region. Theseenhancements have large transverse momentum which rules them out as being dueto pseudoscalar resonances but is consistent with the production ofaxial-vector mesons. We use tagged two-photon events to study the properties ofthe observed enhancements and associate them with the production of f_1(1285)and f_1(1420). Our non-observation of \eta(1440) is inconsistent by more thantwo standard deviations with the first observation of this resonance intwo-photon collisions by the L3 experiment. We present our estimates for 90%confidence level upper limits on the products of two-photon partial widths ofpseudoscalar hadrons and their branching fractions intoK^0_S(\pi^+\pi^-)K^\pm\pi^\mp.
