Comic Valentine, "A Swell Head," circa 1855

From the 1840s into the early 1900s, some people sent inexpensive Valentine's Day greetings that chided, warned, or insulted the recipient. An exaggerated, often garish cartoon and short verse described and dismissed someone's looks, intelligence, personality, or behavior. Within the atmosphere of a festive holiday, under the cover of humor, these "vinegar valentines" were acceptable critiques of behaviors that deviated from social norms.
