I made a vintage mini pocket letter as a RAK for one of my facebook groups. A RAK is a random act of kindness, basically you make or just send something just for the heck of it to someone else.
I took some vintagey travel ATC backgrounds from Hobby Lobby and decorated them. For the first one, I added a vintage picture (I don't know if it's an actual photograph or just a picture). I added a banner and some words to the top. For the second one, I added the 'air mail' ephemera and the train to the bottom, I added some ink to the train piece. For the last one, I added the bird picture and layered some flower punches and a heart punch.
