Giving romantic Valentine's Day cards slowly came into fashion during the 18th century, but they were mostly DIY affairs at the time. By the end of that century, pre-printed cards began to appear, and once the printing and manufacturing technologies of Victorian Britain picked up, the Valentine card industry boomed. Not all sentiments were romantic—some were downright rude—but the tradition of giving friends and loved ones cards has only continued to grow (it's estimated that Americans will spend $1 billion on cards this year alone). Below are 31 cards from years past.
