Mom recently told me that when she was little (1950’s) there was a miniature loaf of bread. Typical white, like Wonder Bread or Taystee. It was not much bigger than two or three hot dog buns and to this day she doesn’t know why they made them.I recall going on a school tour of the Helms Bakery near Los Angeles as in kid around 1958 or so and they gave us miniature loaves of bread as a souvenir.
