Bonjour
Je pensais =C3=A0 des commentaires moins philateliques. On a le timbre qui =
sert =C3=A0 acheminer un message cach=C3=A9.
Par exemple une carte postale avec quelques mots non compromettants lisible=
s par tous, et un rendez vous amoureux =C3=A9crit pour celle qui sait o=C3=
=B9 le trouver...
Ce proc=C3=A9d=C3=A9 a certainement =C3=A9t=C3=A9 utilis=C3=A9, il faut dis=
poser d'une encre qui traverse la colle sans impr=C3=A9gner le recto.
