I found this great card at Kisan Concept Store in SoHo. Kisan is also located in Iceland (!) When I mentioned to the sales clerk that Bjork is on the cover of Interview magazine, she said that that the owner of Kisan has some kind of indirect connection with the singer of Icelandic origins. (I'll confirm with the owner to find out what the connection is.)
The card, by Paper House Productions, is entitled Watercolors.On the back of the card, they explain that "The art of watercolor [...] has been in existence since the primitive hunter gatheres used water and pigment to depict scenes on the walls of caves."
