60 or more galleries--- This is a highly established
artist whose values are stable across the board. There
is a lot of competition at this stage for the artist's
work, but these artworks can be somewhat like money
in the bank because they really are worth what you
pay for them.
If the artist is in 100 or more galleries consider this
like climbing Mt. Everest... twice! A representation in this
many galleries means a very large collector base feels this
artist's message and expressions are of importance and
should be unconditionally shared with others. This builds
heavily towards future values of your investment in the
artist's work. However, you will find these works to be quite
pricey; galleries will be stretched much too thin to have
originals readily available, and you should easily expect
to pay a premium for owning one of these pieces.
