Saw this card at a store--I forget which one--and had to have it. A really cheesy cheesecake photo on the front of a Halloween card? Oh yeah, that's for me.
It's a Hallmark card, so is likely found at any major retailer that sells cards.
If you like gore*, Hallmark has a "splatter" e-card for Halloween! It's available for sending when you subscribe to their online card service for one year, which costs $12. But you can watch and preview the card without subscribing here.
