These comics appeared in our local newspaper for many years. I think my sister collected every single one of them in a scrapbook.
Here's a little history from Wiki:
Love is... is the name of a comic strip created by New Zealand cartoonist Kim Casali (Grove) in the late 1960s. The strip is now syndicated worldwide. The cartoons originated from a series of love notes that Casali drew for her future husband, Roberto Casali. The strip was first published in 1970, under the pen name, "Kim," and was syndicated soon after. 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." 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.
