If there's anything better than geeky Valentine's Day cards, it's superhero valentines — you know, the ones you used to pass out in grade school. If you never thought you'd see them again, then you'll be happy to know we found these gems just for you. From the vintage to the more modern, these valentines are filled with puns ("you're purr-fect") and pleas ("let's be friends") you won't be able to pass up. Give 'em to your loved ones and keep some for yourself — they're that cool.
