Thanks MP and OS for the follow-ups.
Could the box be a "sanitary outdoor bedroom" as advertised by the Hotel Cecil?
As OS noted, 1888 date was provided by the source. Some of the dress seems to be from a later period, but difficult (for me ) to tell. Noticed a sign on the right of the building remincent of a telephone advert, but image is likewise not that clear. AAA? Free Color TV?
