A friend of mine purchased a lab about 20 years ago after it went bankrupt.

He found 60 -80 Marilyn Monroe Discovery Series Cibachromes.
They have been stored now over 20 years in dark storage and has asked me
what I think the value of them are.
The original prints would have sold for around 2.5 k each. These are run offs of the exact same pieces and are in good shape.
attached is the series I am talking about

I have no idea of what they are worth and wondering if anyone has any ideas or leads to people who may know.
