Andy Lippincott. He was introduced in the 1970s as a law school classmate of Joanie Caucus. She was attracted to him, they became friends and seemed to be moving towards romance, and he then revealed he was gay. He appeared off-and-on after that, but this strip is probably from his battle with AIDS in 1989-90. He may be the only fictional character with a panel on the AIDS quilt. I remember reading these strips when I was a kid, and it was one of the few sympathetic depictions of homosexuality and people suffering from AIDS that I saw at the time (times have changed).
Does anyone remember what year this set of strips ran in? Tried a quick googling and didn’t find it.
