After posting about the great retro valentines available at Fred Flare, I did a little searching to see what else I could come up with.
I was pleased to find a great collection of vintage valentine images over at 7 Deadly Sinners, some of which, like the Freudian banana card pictured here, can be just a little bizarre.
Plus, Perpetual Kid offers another set of retro valentines for purchase, comprising 10 really awesome space-themed cards.
