The structure shown above from the 1930s was the Hambro block. “Hambro” almost certainly is a reference to the private London (UK)-based bank. Sort of a boring building, you say? I tend to agree. The exterior was quite dull – and the exterior of the current occupant of this property, unimaginatively named after its address, 777 Dunsmuir, is likewise so (although there are a great many more floors of architectural dullness in the case of the current occupant).
The two interior images shown below are of a business within the Hambro building, a stock/bond brokerage called E. J. Gibson Company. The shots were taken by Vancouver professional photographer Stuart Thomson a few years after the exterior image was made. The interior, like the exterior, doesn’t appear to have been long on charm, but I think there are interesting elements in both photographs.
