In the late 19th century, Valentine's Day was more than an occasion for lovers to express their love for each other by sending greetings cards and presenting gifts. It was also the day for haters to hurl abuses and insults to those they didn’t love. Known as vinegar valentines, these cards carrying caricatures and satirical rhymes intending to vilify, mock and hurt the recipient was available in stores across America and Europe alongside beautiful valentine cards adorned with hearts and flowers. Often, these cards—both valentine and vinegar—were produced by the same companies.
