This advertisement shows the inevitable: the business was commercialized.
The advertisement borders on the renegade as not all sanitariums and hospitals can offer legitimately helpful treatment.
It also makes the rather large statement that unsatisfactory dreams can be prevented.
As Convenience practitioners have experienced throughout the centuries, this is not often true. Nor can unsatisfactory dreams always be cured.
Nevertheless, the advertisement does make the potential client aware that institutional help is available.
Choosing the appropriate institution is of paramount importance.
