Mr. Archibald Scape, America’s foremost composer of backs of cereal boxes, will be at the Food Festival supermarket in Blandville tomorrow afternoon from 2 to 4 p.m. signing copies of his latest work, Fifteen Fun Fiber Facts, on the back of the new Brenneman’s Fiber Friends cereal package. Mr. Scape is best known as the author of Diet and Exercise Make a Perfect Team on the back of Brenneman’s Rice Ripples cereal, and A-MAZE-ing Mazes on the back of Jimmy’s Cracked Corn cereal. Some critics, citing similarities in style and vocabulary, have suggested that Mr. Scape may also have written the box backs for some of the Food Festival house-brand cereals, but so far Mr. Scape has refused either to confirm or to deny these rumors.
