Richmond cigarettes were produced briefly in Canada by Imperial Tobacco, which introduced the brand in 1968 as a filtered king-size. It was Imperial's first and only brand which used the Strickman Filter, an early high-filtration filter tip which was thought to reduce particulate matter in the smoke more effectively than the standard celluose-acetate filter tip. These claims were later disproved, and the brand was withdrawn by the early 1970s.
