Thanks for your comments , talesof , DANTE5 & lux .
I was stunned to find it .
I was prepared to pay way more than 150X what I did .
The seller , who really should have done a little research , did not do said research .
If this is not an example (another exact) of "Let the Seller Beware" I don't know what is .
My Art Conservator is still aghast , esp. since all my involvement with the first .
I do claim credit for having a very good 'radar-network system' when it comes to finding specific items ; the rest however , I really can't explain in very rational terms .
Suffice to say that , along with a few other things - I've had a long run of dumb luck happening around me .
The really big deal to me is that this new painting goes a long way towards changing a hypothesis into a valid & evidential theory . Many questions about the validity of origin in the body of work by the artist have new evidence that is now under scrutiny ( by 'experts' , some of whom were somewhat misled by assumptive opinions ) .
My homage to Elisabeth Sonrel is to bring to light these examples of her work that had been forgotten , and have them added to the 'book' on her history .
The fact that she did no other 'limited edition' series (that have been discovered , to date) painted in her own hand says something about them .
She was 38 when she painted the original , and 30 years later , chose to paint these .
The next chapter in the story is to find out "why?" .
