Pundamental question: Why would anyone choose just any valentine when they could choose one with a pun? These are the things that keep me up at night.
Actually, no. But I do have a soft spot in my heart for a good valentine pun and the valentine section of my shop is filled with them.
Bonus: history is on my side. There is a long tradition of vintage valentines that are simply filled with the worst (best!) puns you'll ever find. Take a look at these beauties from the early to mid 20th century. Swoon!
If you're like me and find these more punny than punishing, check out this genius collection of vintage valentines from Flicker user ValArt2008. So much pun!
