You may be referring to the colour plates by Frederick T. Chapman in "Cadet Grey: History of Life at West Point as seen though its uniformss" (New York, Sterling, 1955) by Frederick P. Todd. I seem to recall that the plates were also sold seperatly at the Academy's shop in the 1960s. Colonel Todd was a COMPANY founder and Mr. Chapman drew many MUIA plates in the COMPANY's first quarter century.
You should be able to secure a copy of "Cadet Grey" from antique book sellers.
