picasso jacqueline blue  14.8.58
picasso jacqueline blu  
I bought this piece at an auction for $15,500 total.  COA by Daniel Nathan isen.  Supposed to have picasso's signature in pencil.  now I'm questioning authenticity.  Did I get scammed?  date in plate is 14.8.58.  Thank you.  eric

It's difficult to make blanket statements about anyone in the industry without doing more research. We do have a contact that is more familiar with Isen's certs.

Please send an email (not in this system) to my personal email address with the image attached, your name and ph# and we will check it in more detail. (Include your text from this site as well)

I can answer questions about Salvador Dali. While I cannot do FREE APPRAISALS, I might be able to help you sell your works. I can also help with Chagall, Miro, Picasso and other 20th Century Masters.

Questions about a type of art or medium can be answered with one response in most cases. Technical issues are easier to deal with than specifics about an artist. If you need help finding values or history on an artist, it will probably involve research that can sometimes take hours to complete. If you have more than one image to send, I will give you an alternate email address as this system cannot handle multiple images.
