Yuruliku Design, known for making stationary sexy again, has designed a set of train postcards (¥378) using four of the major train lines in Tokyo.

The illustrations are not only adorable, but they’re actually shaped like trains rather than your typical 3” x 5”. And for those who find nostalgia in the pre-redesigned trains, the flipside of each postcard reveals the old design. Click for more images at Spoon & Tamago below!
