In searching quickly for a picture of the Pen here in St. John's, I got this hit back from google(tm).
It is a paper by eminent historian Peter Neary on venereal disease and the administration of public health under the Commission of Government [1930s and 1940s].
Fair warning: There are some grim descriptions of disease in this paper, including one of a child admitted to St. Clare's Hospital but subsequently treated successfully with then-new penicillin.
Other than that it is a fascinating glimpse into the relatively recent past.
