Do Not Open is the personal project of Erik Marinovich, a letterer and designer based in San Francisco. Erik remembers the good old times when you wrote a letter with a pen to your best friend. Over the years he got shirts, books, posters and more stuff from his friends. As a reply he began mailing out oversized hand adressed envelopes with a note inside saying thank you.
Some the recipients posted their envelopes to their instagram feed to show it to the audience. Do Not Open brings something that was specifically available to friends and family to the general public. All of them are one of a kind and that makes them rare, unique and awesome. Enjoy this awesomness!
