While no complete script or list of Prof. Mack's cast of characters has yet been found, there are numerous mentions of specific characters and bits of action scattered throughout the various newspaper clippings, press notices, and handbills in the orginal collection of memorabilia. From these it is possible to construct a rather large cast of characters and to recognize some familiar content and action.
A search of all the materials in the Prof. Charles Mack Scrapbook yielded at least one reference to each of the following Punch and Judy characters. Those that were obvious alternate names for a character are listed on the same line. Most are recognizable as regulars from the British versions of Punch and Judy while several appear to be uniquely turn-of-the-century American or Prof. Mack originals.
