Let's Get Acquainted Clover

Penny King gumball machines were small and designed to sit on a countertop. They typically had a body made from cast aluminum and a globe made from glass. For just one cent, they dispensed pin-back buttons as prizes during the mid-twentieth century. Buttons that read “Quit Your Kiddin’,” “Hot Dogs,” and “Let’s Get Acquainted” were just some that could be collected from these machines.

Clovers are a symbol of luck. To get acquainted, is to get to know someone, and in some cases, the term "get lucky" has also been used in conjunction with this phrase.
