I can remember three Mix-O-Vial products being made in Building 41 during the 1980s - Solu-Cortef, Solu-Delta-Cortef and Solu-Medrol. The first pics are official photos of Mix-O-Vial products. Then there are some defect samples used to help train inspection workers. After that, the articles are from the July 1957 and April 1959 Overflow magazines. The first one urges Upjohn salesman to let the physicians satisfy their urge to push the plunger, using a demonstration package with colored water. The son of the Mix-O-Vial, the Acto-Vial, is still manufactured today by Pfizer in Building 41.
