OH. MY. GOODNESS. I just discovered the most delightfully devious chapter in Valentine's Day history, and I had to share it with you all! So get this — before Valentine's Day became this saccharine celebration of love, there were VINEGAR VALENTINES. Yes, you read that right! These were intentionally insulting, brutally honest cards that people sent to mock their crushes or rivals. Luke Honey's piece on Collectors Weekly digs into this absolutely fascinating tradition that completely flipped the script on what we think "love letters" should be. While modern Valentine's industry is worth a whopping $20 BILLION with 145 million cards exchanged annually, these historical vinegar valentines were the ultimate collector's item — snarky, satirical, and surprisingly creative in their cruelty! This is such a treasure trove for anyone interested in greeting card history, vintage ephemera, and the evolution of holiday traditions. The contrast between today's commercial romance and this cheeky historical practice is just *chef's kiss*. Absolutely must-read material for collectors!
