Love Is... is the name of a comic strip created by New Zealand cartoonist Kim Casali (née Grove) in the 1960s. The cartoons originated from a series of love notes that Grove drew for her future husband, Roberto Casali. They were published in booklets in the late 1960s before appearing in strip form in a newspaper in 1970, under the pen name Kim. They were syndicated soon after and the strip is syndicated worldwide today by Tribune Media Services. One of her most famous drawings, Love Is...being able to say you are sorry, published on February 9, 1972, was marketed internationally for many years in print, on cards and on souvenirs. The beginning of the strip coincided closely with the 1970 film Love Story. The film's signature line is Love means never having to say you're sorry. At the height of their popularity in the 1970s the cartoons were earning Casali £4-5 million annually.
