Through another maker. I just found out about this amazing museum on the South Side. It’s Made in Chicago collection is on display starting this month through April, 2018. The website by itself is a great compilation of all the things invented and/or made in Chicagoland and makes for great reading. Look up Scwhinn and Radio Flyer or even Rock-Ola juke boxes and Zenith Radios and, of course, Motorola.
