Hello everybody.
I am looking for this stamp

As you can see, it looks to be number one of the sheet.
But because there is no information about roller flaws for this stamp, I need another one to compare and find details.
If you do not want to sell, I will be happy to get a scan (300 dpi) to keep going.
Many thanks
Laurent
