Identifying an architectural logo
Can any reader of this blog help identify the building represented in the following embossed symbol on a sheet of paper used by RLS:
The paper was used for pencil draft versions of five short fables, including ‘The Carthorse and the Saddle Horse’ which we can date to after November 1890 when the horses referred to arrived at Vailima. The embossed ‘logo’ is in the top left-hand corner of the unlined paper, which from the photographic image (the measurements have not yet been taken) appears to be foolscap, not writing paper—so working paper from an office rather than letter paper from a hotel or club. The architecture (the slim dome on a drum, the suggestion of a portico and the symmetrical side buildings with gabled roofs) also suggests an institutional building.
Does any reader of this blog recognise the form from their knowledge of Victorian architecture (perhaps now destroyed) of Sydney, or Honolulu (but were there any domed buildings there?) or perhaps even San Francisco? Or has any researcher come across paper with the same embossed symbol?
