This last cover is a an official First Day Cover featuring the values of the 1965-1973 Wildlife Issue that were released on May 2, 1966. FDC's of this issue are seldom seen - this is the second one I have seen in almost four years, the first one slipping through my fingers on e-bay. I like this cover especially because it has been signed by the designer of the stamps, Maurice Fievet. As always, I welcome your comments on these covers, as I am keen to learn as much about them as possible.
