Online Art Valuation

Although very raw, and I'm guessing he is an editor (not aware of my art definitions) ... But I have an impression of Marilyn Monroe "Peaches and Cream" by Olivia, numbered canvased on a black backboard. I have been very successful in finding a similar position in online assessment.

Any ideas what it may be useful assuming it's in excellent condition?

There is a similar item on eBay for $ 15, but it is not numbered so you should be more valuable.
Try contacting the vendor and see if they can help you.
