This April 03, 1946, photo from the Spokesman Review shows Dave Zimmerman and his band/radio show ensemble stuffed into a jeep. With a Detroit transit strike raging, a borrowed jeep was the only way to get everyone to their radio show gig.
According to this page, Dave Zimmerman was a long time announcer at WWJ in Detroit. He hosted a popular radio program called Coffee Club and was on the air for Detroit’s first television broadcast from the 47th floor of the Penobscot Building.
