Keep Circulating the Tapes/Newspaper Comics

While U.S. Acres will hardly get reprinted, the strips are available, in color, on the official Garfield website - though they're releasing one per day, and only started in August 2010.
Dick Tracy has few reprints available and in the case of the Max Collins era strips (which were critically acclaimed) few have ever been reprinted, save the various sequences collected in the Anniversary editions. Fantagraphics is releasing The Complete Chester Gould Dick Tracy archive editions however, and The Collins Case Files are currently on its third volume.
