Probably the one of the most unusual applications of a stencil happened in 1964 when Union Carbide [then-owner of the still-new line of 'Thankful' brand plastic wrap and storage bags] sponsored a $100,000 contest to compare a stencil of their logo design in order to win a prize.
The publication ad informed of how one thousand fortunate individuals would win $100 by just taking a die-cut stencil of the brand to the store and overlaying it on the logo printed on the food wrap box to see if it lined up completely.
The hand-lettered title announcing 'match the stencil and win' was performed in a casual sans style and showed the cheerfulness of many typestyles found in ads during the late 50s and early 60s.
