2 examples of covers ruined by unscrupulous postal workers!
As I mentioned I enjoy preparing covers, FDC's or others, with my own touch. Sadly enough you never know what will happen to them once they leave the post office.
Over time I developed a great relationship with Annick who is the postmistress where I go. She even lets me cancel my own envelopes.
As you can see below these 2 covers were cancelled on the first day of issue but unfortunately when they arrived at the main post office they were cancelled again with a different date and mechanically. What a shame!!
