Nicolette Gray¹ attributes the original design as University Text by Austin/J. Wood, 1862. MacKellar, Smiths & Jordan showed it in 1869 as Crosier. The tradename Morningside was apparently assigned by Dan X. Solo.
Star THP Partner Alan Prescott has done a beautiful job on this early example of a stylized dual-case latin.
