Alka-Selter and Bayer are manufactured at this plant This Miles Laboratories invitation is for the May 14, 1948 open house at the Manufacturing Plant in Elkhart Indiana which currently has Over 12,000 Employees. Great gift for someone who worked / works at the plant or a collector of Alka-Seltzer or Bayer products. This was my parents and was kept in their scrapbook and is now close to 75 years old and has been kept in a smoke free environment all this time. Would look great framed and gifted to a pharmaceutical collector Free Shipping The image of a newspaper article was clipped from the Internet, for reference only and not an actual product Due to the value of this collection, it will be mailed USPS Priority Mail with signature of person over the age of 21 required, thanks
