  How the supermassive black hole SgrA* in the Milky Way Center looks like for
a distant observer? It depends on the black hole highlighting by the
surrounding hot matter. The black hole shadow (the photon capture
cross-section) would be viewed if there is a stationary luminous background.
The black hole event horizon is invisible directly (per se). Nevertheless, a
more compact (with respect to black hole shadow) projection of the black hole
event horizon on the celestial sphere may be reconstructed by detecting the
highly red-shifted photons emitted by the non-stationary luminous matter
plunging into the black hole and approaching to the event horizon. It is
appropriate to call this reconstructed projection of the event horizon on the
celestial sphere for a distant observer as the ``lensed event horizon image'',
or simply the ``event horizon image''. This event horizon image is placed on
the celestial sphere within the position of black hole shadow. Amazingly, the
event horizon image is a gravitationally lensed projection on the celestial
sphere of the whole surface of the event horizon globe. In result, the black
holes may be viewed at once from both the front and back sides. The lensed
event horizon image may be considered as a genuine silhouette of the black
hole. For example, a dark northern hemisphere of the event horizon image is the
simplest model for a black hole silhouette in the presence of a thin accretion
disk.
