Claim Text:
1. A moving step article manufactured using a line printing press, comprising: a first ribbon defining an obverse side of a front cover and a reverse side of a rear cover on a primary ribbon side and a reverse side of said front cover and an obverse side of said rear cover on a secondary ribbon side; said front cover and said rear cover defining a first continuous one-piece unit made of a first single material; a hinge fold positioned between said front cover and said rear cover for pivoting said front cover between a closed position and an open position; a second ribbon defining a lower side of a first spine sheet positioned between an obverse side of an interior leaf and a reverse side of a second interior leaf on a primary ribbon side and an upper side of said first spine sheet positioned between a reverse side of said interior leaf and an obverse side of said second interior leaf on a secondary ribbon side; said interior leaf, said first spine sheet and said second interior leaf defining a second continuous one-piece unit made of a second single material; a primary hinge in said second ribbon between said first spine sheet and said interior leaf for defining a leaf width in said interior leaf; a secondary hinge in said second ribbon between said first spine sheet and said second interior leaf for defining a second leaf width in said second interior leaf; a binder coupling said lower side of said first spine sheet to said reverse side of said front cover for defining a leaf offset dimension between said hinge fold and said interior leaf and a second leaf offset dimension between said hinge fold and said second interior leaf; said leaf offset causing said interior leaf to be displaced relative to said rear cover during pivoting said front cover between said closed position and said open position; said second leaf offset causing said second interior leaf to be displaced relative to said rear cover during pivoting said front cover between said closed position and said open position; a third ribbon defining a lower side of a second spine sheet positioned between an obverse side of an third interior leaf and a reverse side of a fourth interior leaf on a primary ribbon side and an upper side of said second spine sheet positioned between a reverse side of said third interior leaf and an obverse side of said fourth interior leaf on a secondary ribbon side; said third interior leaf, said second spine sheet and said fourth interior leaf defining a third continuous one-piece unit made of a third single material; a primary hinge in said third ribbon between said second spine sheet and said third interior leaf to define a third leaf width in said third interior leaf; a secondary hinge in said third ribbon between said second spine sheet and said fourth interior leaf to define a fourth leaf width in said fourth interior leaf; a second binder coupling said lower side of said second spine sheet with said reverse side of said front cover for defining a third leaf offset dimension between said hinge fold and said third interior leaf and a fourth leaf offset dimension between said hinge fold and said fourth interior leaf; said third leaf offset causing said third interior leaf to be displaced relative to said rear cover during pivoting said front cover between said closed position and said open position; said fourth leaf offset causing said fourth interior leaf to be displaced relative to said rear cover during pivoting said front cover between said closed position and said open position; said second leaf offset dimension having a second greater offset dimension than said third leaf offset dimension; said third leaf offset dimension having a third greater offset dimension than said fourth leaf offset dimension; said second greater width dimension and said second greater offset dimension creating a second step display tab area on said obverse side of said third interior leaf that is progressively revealed adjacent to said outer edge of said second interior leaf during pivoting said front cover between said closed position and said open position; said third greater width dimension and said third greater offset dimension creating a third step display tab area on said obverse side of said fourth interior leaf that is progressively revealed adjacent to said outer edge of said third interior leaf during pivoting said front cover between said closed position and said open position; and said first spine sheet being discontinuous from said second spine sheet.
