We’re not sure what to make of this, but it is definitely not a Zazzle template and not an internet card.  The dog is saying “Hey, I’m Otto, who are you?”.  This card was mailed in 2013 with two stamps–neither one postmarked–and Priority label.  In the lower left corner is a box called “Sormenjälki-terveisin” (Fingerprint regards) and, sure enough, a fingerprint is inside.  That’s the whole idea, apparently.  Grade: 4
