#TodayInHistory: #OnThisDay in 1968, the R40 Slant made its debut in the #NYCsubway system, beginning on the F line. This 1966 artist's rendering from the #NYTMCollection was issued by industrial designers Raymond Loewy and Associates, and William Snaith, Inc to showcase the "new look" of the R40.

From the #NYTMCollection, this spring-loaded token case dates to circa 1960 and has three slots to hold #NYCsubway tokens. By 2003, when tokens were phased out, cases such as this one would no longer be an essential for commuters. Did you ever own a token holder?
