Sliderule Pillows

Description: No battery, no updates, needs no signal. The slide rule has been doing multiplication since 1622, and this one is set to a real one: the slide's 1 sits over 2, the cursor reads 3 and 6. A worn vintage print ad for engineers, math teachers and physics nerds. The version for light garments is here: https://www.teepublic.com/t-shirt/100262392-the-original-pocket-computer-vintage-slide-rule-ad
