It may be interesting to note that Bakelite of Bound Brook, NJ was sold to Union Carbide in 1939 (and later, to Dow Chemical). Since the cover shown is dated October 1939, it was either from a very late usage, or from a old mailing list that didn't yet record the name change, or the company continued on with the name "Bakelite" after the Union Carbide takeover took place.
In connection with the return address of Hansen & Yorke Co., it may be interesting to note that it was later taken over by Graybar, Inc. There is some brief commentary on the internet that this was one example of a well known company (Hansen & Yorke) taken over too quickly by another firm (Graybar) and losing some of their identity in the process. Consider this:
Quote:
...some years ago, Graybar, then mostly an electrical equipment distributor, acquired Hansen & Yorke, a small but successful industrial supply company in the New York area. The target was to be the launching pad for Graybar's expansion into the industrial supply sector. Immediately after closing, the Hansen & Yorke name was jettisoned and replaced with "Graybar Industrial." It was a death knell. Buyers of industrial goods knew the H&Y name, one with 35 years of real customer goodwill. Sure the Graybar brand had recognition but as a faceless giant, not a service-oriented family company.
