Lilly Varnish Co Fine Varnishes Indianapolis Indiana Eyeglass Cleaning Sheets

Description

Lilly Varnish Company, 666 South California Street, Indianapolis Indiana - advertising giveaway - a packet of eyeglass cleaning sheets.  I'm not sure any were ever used.  The package looks almost brand new, although it must be from the 1950s or early 60s.  In a search online, the company was named Lilly Varnish from 1888-1965, when changed it's named to Lilly Industrial Coatings.  I found this in my parent's estate.  I'm assuming my father acquired it through his work as a safety inspector of manufacturing plants and work places, which would have occurred in the 50s or 60s.
