Hoping that Peter will tolerate a different use of this site, I start a thread about postal stationery. Postal stationery come in different forms: postcards,envelopes,aerogrammes (air-letters), lettercards,lettersheets,wrappers and maybe others. But all of them have one thing in common: they are all post-paid ! Usually a stamp is printed on them,but sometimes they show the imprint taxe percue or post paid. In a long collectors life many postal stationery come along and are stored away in different places and boxes. For most it is difficult to find any catalogues,so the value is not to important,because you simply cannot find out,what it is.However if you can,you mostly will find,that their value is pretty modest. To start,here a aerogramm from Ireland.
