Tiki valentine greetings
fliker user LindaK must have been a designer for the now (apparently) defunct hipstercards.com. Her photostream includes two highly appropriate cards for polypop fans to send as valentine greetings.
There's no way to automatically send the cards, so you'll have to handle it the old fashioned way—save the image to your hard drive and include it as an attachment in an email.
