There is no built in obsolescence in this product. Well of course the photos have faded.
Still in production after 70 years.
It is like many of the good things in the past we have easier ways of doing the job now. Back then one man could arrive at the job with two sections of scaffold, a guardrail and four outriggers and safely paint a two story house and still buy flowers for the little lady on the way home. Forgive the nostalgia, but there is more to life than the job.
