Artist J.C.T. Holmes created these notecard sets featuring either Wind Waker or Peach/Rosalina themes, for $8 each (per set of 6). I love the idea of writing people letters on something that looks like it should be used to send a powerup to Mario!
The adorable GIF comes from Thilink, and is one of many lovely tributes to the Mother series I came across today. Check out these other awesome Earthbound pieces from Layeyes, KurkoBoltsi, and Melissa King.
