Query: P-parity of charmed particles from associative photoproduction of D and
  D^*-mesons   We suggest to measure the triple polarization correlations in the exclusive
associative charm particle photoproduction, vector gamma + vector p --> vector
Lambda_c^{++} bar{D^0} with linearly polarized photons, as a method to
determine the P-parity of the charmed D-meson. The dependence of these
correlations on the parity P(N Lambda_c D) can be predicted in model
independent way. The t-dependence of the differential cross section for vector
meson photoproduction, gamma + p --> Lambda_c^{++} bar{D^{*0}}, in a model
based on D-exchange, is also sensitive to P(N Lambda_c D).
