I love letterpress and the whimsy of it when it is applied so simply. So these two card companies are just a hoot! Check out Paper Medium with their super cute illustrations and funny little creatures. I like the little pop of color and the witty sayings - in the second image it says "We raise this toast in honor of your birthday." Toast? Get it? :)
Salt & Syrup is from Stockholm, and they make cards with simple graphic shapes of animals - with the name of the animal in French, Swedish and English. Very sweet.
