This Stamp is very “special”! It has been printed half a year before the “TuSello” Service has been started! The analisis of the Dot-Code shows the following data:
Row and column parity verified correctly. Printer serial number: 027785 [or 37027785]
Date: July 10, 2006
Time: 04:39
Column 15 value: 118
Of course, I checked this several times, but always the same result: The Date is not correct! What could be the reason? Did somebody change the Systemdate of the XEROX Printer?? And if, why? Was is a mistake, was it wanted??
To anwer these questions I need to explore some other TuSellos printed in that period of time (March-April 2007). If you want to help with this investigation, please send me scans in minimum resolution of 600 dpi, better 1200 dpi. The best is to have a big white part of the edge.
