This is a drawing that I found at an art auction last year of household effects. I cannot make out the signature. Maybe it says Shinoski or some other Japanese name. Not sure. But it appears to be some sort of chalk or pastel paint. It seems fashion related. It measures 35 inches by 30 inches in the frame.
Thank you for contacting Mearto with your appraisal inquiry. So that I may best assist you, can you please upload a better image of the signature? Can you see anything written on the reverse of the work?
