hmm two thumbs down for my last answer... I need to amend it.
Art has no financial value.
....but they sure make great comments on MySpace and social networks....
but the value is the concept and idea.... not the physical market value of it.
as for something like an old painting... yes.... but it is less art and more a historical artifact.
...back in the day someone could make something special and people would pay money for it even if it were new.
I am an artist. I am speaking from experience inside the market. MARKETING myself and many many others.
I have spent the last four years marketing artists by selling advertising in the industry.
trust me....
your shit is worthless.
