Limited Edition-Special First Day Cover
To commemorate the 2018 Endangered Species stamp series, a limited edition first day cover in silk has been produced by UNPA. A single stamp, one from each office, is affixed and cancelled, as appropriate, from New York, Geneva or Vienna. The covers are consecutively numbered.
The covers will automatically be provided to customers who maintain a standing order account for New York “miscellaneous products” (art. 424).
Non-standing order customers should place orders early so as not to be disappointed.
