I just received this adorable postcard today, from Carla of 365 letters blog. Squee! Love the cute pony express postman riding through a forest. Probably not terribly historically accurate to what the pony express was really like, but hey, it's so CUTE! The postcard is made by the Rifle Paper Co.
Edit: Thanks to blog reader and letter blogger Anne of Letter Love for spotting these postcards on the Paper Source website.
Good mail day - thanks, Carla!
