In the 16th Century official letters, and letters sent by important people, were mailed, as Grand-Cartiret puts it, "under cover or envelope." The message was enclosed in a paper that was folded and sealed.
Each sender had to take care of his own "enveloping," and would cut the paper as he saw fit.
The few specimens that have come down through the years are obviously individually made, with no uniform cut or pattern.
No one will ever know who it was that first conceived the idea of cutting paper for envelopes from a standard pattern. No doubt it was a stationer who sold paper, and realized that there was a
need to be filled. The stationer who first folded and fabricated envelopes by hand has no monument to mark his achievement, unless the hundreds of envelope-producing plants all over the world be
considered as such.
On July 31, 1635, King Charles I issued a proclamation from his court at Bagshot establishing the first State postal service for the conveyance of private letters in England and Scotland, and
appointing one Thomas Witherings, Esquire, to organize and manage the new system.
A strikingly modern idea was tried out in France in 1635. M.de Valayer obtained the permission of King Louis XIV to establish a postal system in Paris. He set up boxes at street corners, and
announced by handbill that he was prepared to deliver any letters placed in them provided they were enclosed in the envelopes that he place on sale at certain stores.
These envelopes were in the nature of wrappers, but as they contained a printed receipt for postage paid, they were, at least in idea, amazingly like the government stamped envelopes that came along
nearly 200 years later.
De Valayer's scheme failed, and it is generally thought that it was sabotaged by certain interests who feared its success. At any rate the whole idea was ridiculed, and any chance for success that it
might have had was ruined by the dumping of refuse and live mice into the receiving boxes. Naturally, the public would not use a service so undependable, and de Valayer had to give up.
