/* Barry Harris: the method. Record-sleeve design: five part inks on sleeve board, Archivo for structure, Bodoni italic for Barry's own words.
   Six inks, printed like a two-colour sleeve: Paper, Black and four spot colours.
   Colour belongs to the method only: each of the five parts owns one ink,
   and every stage of that part is printed on that ink. */
