what is the value of a salvatore dali signed etching of rhinoceras?

Have the item checked for authenticity. Do you believe it is a real etching or a copy?

From what I found, if it is truly a Dali, it's worth anywhere between $125 -$4000. But that's just based on what I found online.

Best to take it to a specialist that can do his/her due dilligence.

If it is a true etching by dali, it would be worth millions. Do you mean a signed print of this etching? There are many, signed print and numbered would be worth in the thousands.
