Stationery purveyors J.C. and Rollie Hall ran into a problem during the 1917 holiday season: Business had been too good at their Kansas City, Mo., shop, and they'd run out of the white, red, and green tissue papers that were the era's standard gift dressing.
Poking around the shop, Rollie realized they still had a stack of fancy French paper meant for lining envelopes. On a lark, he placed the lining paper in a showcase and priced it at 10 cents a sheet. The paper sold out instantly.
Now you know who to blame.
