Upjohn pharmaceuticals were orginally shipped in sturdy wooden
boxes made from 5/8"x 8" boards with wooden corner posts. These
would have made locally for the company. This lasted until
after WWII. When plywood became widely available, Upjohn
shipping containers were then switched to 1/8" plywood with
metal brackets holding all the wood together. Company logos were
added using stencils. A few boxes survive in local collections.
