The TPC/Two-Gamma Collaboration has measured the inclusive cross section for production of charmed D*± mesons in photon-photon collisions. The reaction utilized was e+e-→e+e-D* ±X, with D*±→D0π±, D0→K∓π±, and either zero or one outgoing e± detected. The result, σ(e+e-→e+e-D* ±X)=74 ±26±19pb, is in agreement with the quark parton model prediction for e+e-→e+e-cc̄, combined with a Lund model for the hadronization of the charmed quarks.
