Holy box of chocolates, Batman!
Just in time for the holiday, we've found these super mod valentines from the 1960s featuring Batman, Robin and the rest of Gotham's superheroes and villains.
Mark Anderson originally found the cards on eBay and decided to scan them for all to see.
The cards were released in 1966, the same year Batman premiered in primetime with Adam West as the titular superhero and Burt Ward as his sidekick, Robin.
Because of the show's popularity, these Valentine's Day cards were surely a hit in classrooms around the country.
We can imagine fans of the superhero swooned upon receiving a card with Batman saying, "You make my heart go va-roooom."
