Digging through some old newspapers on Google News Archives I stumbled across "Cinderella’s Christmas Crisis" in a November 30th 1981 edition of the Reading Eagle.
According to Mouse Planet this strip ran from November 30th to Christmas Eve 1981 and had the following staff: Carl Fallberg (writer) Tony Strobl (pencil) Steve Steere (inker)
It doesn't look like anyone else compiled this little gem online so I will do it here.
The story is told in serial fashion and has to do with Cinderella trying to get letters from orphans delivered to Santa. The story features a fun surprise cameo from another Disney movie.
The strip ran daily skipping 12/7, 12/13 and 12/20.
