A Providence naturalist’s bookmark, a potentially useful RPG prop or story prompt. From a Providence notebook of 1897. Lovecraft knew Westminster Street well, and the prospect of obtaining “preserved” animals or curious “fresh specimens” there seems to offer much scope for Mythos fiction.
Update:
A Google Books search for: ‘354 westminster providence naturalists supplies’ reveals Southwick & Critchley “…from either dry skins, or fresh specimens”.
It’s a vacant lot now, but if you head North on Westminster you’ll eventually come to The Arcade today containing Lovecraft Arts & Sciences.
