This Sheet is Classic Series No.8. The front and the back of the M. Sheet are in excellent condition, no hinged mark on the back of the M. Sheet, and it is in off white aging coloured. This item has been in my collection for the last 20 years.
A very scarce stamp. This is a nice looker but is not perfect. In my view it has a streaky thin running from the “A” of China down the portrait tablet. I originally thought it was a colour run, but this is not the case and the pictures show the thinning clearly.
