I have not found a comparable sale record by this artist for you.
I will opt-out and your question will open again to all the experts. If someone knows the answer they will post a response to you here. You do not need to re-list your question and this does not cost you extra. There is not a guarantee that you will receive a response.
I will not be able to respond back after opting-out
I do hope you find the information that you seek.
