We discuss NMSSM scenarios in which the lightest Higgs boson $h_1$ is consistent with the small LEP excess at 98 GeV in $e^+e^- \to Zh$ with $h\to b\bar b$ and the heavier Higgs boson $h_2$ has the primary features of the LHC Higgs-like signals at 125 GeV, including an enhanced $\gamma\gamma$ rate. Verification or falsification of the 98 GeV $h_1$ should be possible at the LHC during the 14 TeV run.
