- Comic Valentine, "Book-Keeper," 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.

- Underwood Sundstrand Adding Machine, circa 1946 - Mechanical adding machines were indispensable office equipment used before the computer era. These devices were perfected by the American Arithmometer Company in 1886, spurred on by William Seward Burrough's desire to reduce drudgery in clerical arithmetic work. Transistors and electronic desktop calculators displaced adding machines in the 1950s; by the 1970s, microchips reduced calculators to the size of a shirt pocket.
