  We initiate the studies on the structural physics of the tower of stable
large-$N_c$ mesons through a first computation of the collinear quark-structure
of a large-$N_c$ pion using lattice Monte-Carlo methods. We adapt the
large-$N_c$ continuum reduction for the determination of meson correlation
functions involving the spatially-extended quasi-PDF operators as a perfect
strategy to concentrate only on the short perturbative length scales. We find
the internal structures of pion in the large-$N_c$ and $N_c=3$ theories to be
quite similar. Interestingly, we find hints that even the observed differences
could arise to a large extent via the different perturbative QCD evolution in
the two theories from similar initial conditions at low factorization scales.
