New type of postal and advertising envelope, based on the model already known, and that is not claimed as such, of those that have a closed window with transparent material on their front wall so that through it they can read the address written directly on the paper of the letter, characterized in that the desired advertisement is printed on the part that is to be the front face of the back wall of the envelope and in such a place that, when the envelope is made, said advertisement coincides with the window of the front wall, so that this ad, invisible while the envelope carries a letter enclosed inside, begins to be visible through the transparent material of the window as the letter is removed and becomes fully visible when the envelope is empty.
