I have two of this style drawings. Different images. Collected by my Great Aunt in the late 50’s early 60’s. She kept them flat, in a plan file until she pass away in 1965 I’ve kept them the same way. Flat, out of the sun. They look like they are painted on silk. 10”x 12”

This is an unsigned early to mid 20th century portrait bust painting on silk. Based on the style of the headpiece, this is an image depicting the Emperor Shenzong of Song who ruled from 1067 - 1085. These were usually created for export as 'exotic' wall decor from the Far East. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
I've added two more images. There is no shaved cork. Looks like silk fabric. The images are mounted on some sort of dark paper. Hope these images help. Thanks again.
