I have a small painting approx 8 x 6 .  It is painted onto a sheet of
copper.  It is painted in oils.  It depicts a ship at sea with sails
billowing and is signed g. Bellini.  The frame is hand carved wooden.
How can I tell if this is a genuine Bellini?  I do not have a copy of
Bellini's signature.  I can email a copy of the painting to you.
Also, I took it into the National Gallery in London and Dublin they
maintain that yes it is old but as Bellini's work was mostly religious
they don't know
if it is or is not the genuine thing. Even  If it is a fake surely it
must have some value?  What is its value if it is real?
