The slide rule fits into a clear plastic bag and then into an orange-brown leather case lined in clear plastic.

The slide rule arrived in a white, black, red, and yellow cardboard box. The 1958-1962 Pickett logo is superimposed on a model of the atom on the box. The top and bottom of the box are marked with several of the instrument's selling points: lifetime accuracy, all metal permanence; select a handy pocket size rule too (/) matched for your convenience by Pickett; micro divided scales; world's most accurate; safety liner case; completely guaranteed; complete instruction manual; slider tension springs.

The logo, nylon indicator with flat lens, straight style of posts, and company addresses in Chicago and Alhambra, Calif., are all consistent with a date around 1960. However, according to the donor, the slide rule was given to him by his parents as a Christmas gift in 1944.
