Yes, that's right, every stamp has individual field marks. Also the print was quite rough. This is not what I'm talking about.
This stamp in the auction has the wrong color and the print is too unclear, please just compare the sharp lines in the sample of the one cent stamp (the block of 4) with the blurry lines in the two cent stamp.
Sure you are free to believe that this stamp is not a forgery. You can also believe the earth is disk and not globe. You are invited to ask other experts for confirmation. The contact of other experts you can find in my post earlier.
Note to the buyer of this stamp: Please let it expertize by AIEP (http://www.aiep-experts.net) or Experts & Consultants Ltd. (contact is Mr. Poon) in Hong Kong.
