Abstract
We show that pseudoscalar-meson production by two off-shell photons ca n be used to check the Brodsky-Lepage model for two-photon exclusive c hannels in QCD versus the vector-dominance model. The behavior of the form factor of the Mgammagamma* vertex is indeed quite different in e ither model.
