  A local void in the globally Friedmann-Robertson-Walker (FRW) cosmological
model is studied. The inhomogeneity is described using the
Lema\^{\i}tre-Tolman-Bondi (LTB) solution with the spherically symmetric matter
distribution based on the faint galaxies number counts. We investigate the
effects this has on the measurement of the Hubble constant and the
redshift--luminosity distance relation for moderately and very distant objects
($z \approx 0.1$ and more). The results, while fully compatible with
cosmological observations, indicate that if we happened to live in such a void,
but insisted on interpreting cosmological observations through the FRW model,
we could get a few unexpected results. For example the Hubble constant
measurement could give results depending on the separation of the source and
the observer.
