This is a 20th century, vintage, original, 1960s framed painting on velvet depicting a 'Keane' era style big eye boy who is crying. The frame is a style that came out of Mexico in that era, however these were also sold through Hawaii. Your big-eye painting is not by Keane; the signature appears to be Kety or Ketu, which is not a listed artist. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
