Love Is... is 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 Content Agency. 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 early to mid 1970s, the cartoons were earning Casali around five to six million dollars annually. Roberto Casali was diagnosed with terminal cancer in 1975 and Kim stopped working on the cartoon to spend more time with him. Casali commissioned London-based British cartoonist Bill Asprey to take over the writing and drawing of the daily cartoons for her, under her pen name. Asprey has produced the cartoon continuously since 1975. Upon her death in 1997, Casali's son Stefano took over Minikim, the company which handles the intellectual rights. The strip appears daily except Sunday. Comic strip features Love Is... is a single-frame strip. The caption for each strip begins with the phrase "love is..." in the upper left corner, with the thought completed at the bottom, below an illustration, usually of the man and the woman who are the main characters. Each strip is independent of those before and after; there are no ongoing storylines. The two main characters are a man and a woman, drawn simply with oversize heads and eyes. They are typically depicted unclothed, unless clothing is needed for the scene depicted, such as a military uniform for the man, or an apron for the woman. The figures have no primary or secondary sexual features shown other than the woman having dots for nipples. He is identified by his short black hair, and she by her light waist-length hair. The characters have been featured in various stages of romance: just meeting, dating, as a young married couple, and in old age. Although not usually named,
