From at least 1938 through the 50’s the Automotive Service Industry Show at Navy Pier in Chicago was the main place for suppliers to show off their new products. The shows/conventions were highly attended; around 21,000+ people in their peak years of 1947 and 48 and 500-600 manufacturers . There was no show in 1949 and by 1950 the numbers began to drop off. (16,000)
The Alemite display booth was well attended, with a merchandiser displayed right in the center. Some displays cost north of $10,000 at the time, and companies used everything from key rings to smoking pipes to attract visitors.
